How can you predict the following stages of a reaction by comparing the value of `K_(c) and Q_(c)`?
(i) Net reaction proceeds in the forward direction.
(ii) Net reaction proceeds in the backward direction.
(iii) No net reaction occurs.

Text Solution

AI Generated Solution

To predict the stages of a reaction by comparing the values of \( K_c \) and \( Q_c \), we can follow these steps: ### Step 1: Understand the Definitions - **Equilibrium Constant (\( K_c \))**: This is the ratio of the concentrations of products to reactants at equilibrium. It is a constant value for a given reaction at a specific temperature. - **Reaction Quotient (\( Q_c \))**: This is the ratio of the concentrations of products to reactants at any point in time, not necessarily at equilibrium. ### Step 2: Compare \( K_c \) and \( Q_c \) ...
