Solution
Solution Steps
Step 1: Understanding the Reaction Quotient, \( Q \)
The reaction quotient, \( Q \), is a measure of the relative amounts of products and reactants present during a reaction at a given point in time. It is calculated using the same expression as the equilibrium constant, \( K \), but for non-equilibrium conditions.
Step 2: Analyzing the Forward Reaction
When a reaction proceeds in the forward direction, reactants are converted into products. This means that the concentration of products increases while the concentration of reactants decreases.
Step 3: Effect on the Reaction Quotient, \( Q \)
Since \( Q \) is calculated as the ratio of the concentrations of products to reactants, an increase in the concentration of products and a decrease in the concentration of reactants will cause \( Q \) to increase.
Final Answer
The reaction quotient, \( Q \), will increase as a reaction proceeds in the forward direction.
