  I think it's because there are coloured compounds which can indicate a shifting position of equilibrium easily. As K2SO4 was added, it turned light blue, indicating that CuSO4 was formed at a greater concentration than the products. The equilibrium shifted to the left reactants. Heating caused it to shift to the right, cooling to the left. The forward reaction is endothermic. This is because, when heated, the equilibrium shifted to the products turned green to counteract the change and cool the reaction mixture down. Adding K2SO4 - shifts to left - equilibrium constant lowers. Ice - shifts to left - lowers Heat - shifts to right - Kc increases. Get your answers by asking now.

For example, the maximum temperature change that occurs during an acid-base titration signals the end-point of that reaction. The following lab was an acid-base neutralizing titration. You can visualize the process of an acid vinegar neutralization in a titration curve, which is a graph that shows the amount of added base sodium hydroxide on the x-axis and the pH of the solution that you can measure throughout the titration with a pH meter on the y-axis.

• Equilibrium

  Conclusions Use Le Chatelier's principle to explain the changes that you recorded in the table above. Draw a conclusion about the effect of a change in concentration of either the reactants or products on the equilibrium position. Also draw a conclusion about the effect of a change in temperature on the equilibrium position. If the pressure is increased the equilibrium will shift to favour a decrease in pressure. If the pressure is decreased the equilibrium will shift to favour an increase in pressure. When the volume of a system is decreased and the temperature is constant , the pressure will increase. There are more collisions with the walls of the container. If there are fewer gas molecules there will be fewer collisions, and therefore lower pressure. The equilibrium will shift in a direction that reduces the number of gas molecules so that the pressure is also reduced.

  Figure 8. An increase in pressure will: Favour the reaction that decreases the number of gas molecules. A decrease in pressure will: Favour the reaction that increases the number of gas molecules. Consider illustration in Figure 8. Equations a and b are not balanced equations. The effect of a catalyst on equilibrium ESCNS If a catalyst is added to a reaction, both the forward and reverse reaction rates will be increased. If both rates are increased then the concentrations of the reactants and products will remain the same. This means that a catalyst has no effect on the equilibrium position. However, a catalyst will affect how quickly equilibrium is reached. This is very important in industry where the longer a process takes, the more money it costs. So if a catalyst reduces the amount of time it takes to form specific products, it also reduces the cost of production.

• Website Analysis

  This change in reaction rate minimises the effect of the change and restores the concentration ratio between reactants and products. There will just be more reactants and products. The equilibrium then shifts to minimise the effect of the change and restores the ratio between reactant and product concentrations. Therefore the ratio between reactant and product concentrations will remain the same. The ratio between the concentration of the reactants and products will change. Use Le Chatelier's principle to decide how the system will respond. Look at the given equation and decide whether the rate of the forward reaction or the rate of the reverse reaction is increased. State the shift in equilibrium.

• Equilibrium And LeChatelier's Principle

  Where appropriate, link equilibrium shift to any observed change in the system. What would be observed? The reverse reaction is favoured and the equilibrium will shift to the left. What would the colour change be due to this equilibrium shift? Graphs and Le Chatelier's principle Graphs can be used to represent data about equilibrium reactions. The following are some points to keep in mind when presented with a graph. Identify the type of graph by looking at the label on the y-axis. You will find either: a rate-time graph a mole-time or concentration-time graph For rate-time graphs, when the rate for the forward reaction and the rate for the reverse reaction are equal, the system is in equilibrium. For concentration-time graphs or mole-time graphs equilibrium occurs where the concentration or number of moles of the reactants and products are constant.
