12. Consider the simple one-step reaction: Because the reaction occurs in a single step, the forward reaction has a rate of kiomardlAl. What happens to the rate of the forward reaction when we increase the concentration of A? a. mwe B b. How does your answer in part (a) explain the reason behind Le Chatelier's principle? In other words, state how and why (in terms of reaction rates) the reaction at equilibrium will react to an increase in the concentration of A?

Explanation / Answer

a. When the concentration of A is increased, the rate of the forward reaction will increase and more product will be produced.

[The question primarily asks about effect on the rate, and that is why the word 'rate' is encricled]

b. Le Chatelier's principle states that whenever there is a perturbation in any system, then the system reacts in a manner such that the effect of the perturbation is neutralized. If concentration of A is increased, then the only way to decrease it is to increase the consumption of A too. This happens by increasing the forward rate constant.
