Which of the following statements regarding the reaction quotient () and equilibrium constant () is/ — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

$Q_c$ uses instantaneous concentrations (A). If $Q_c > K_c$, the reverse reaction is favored, consuming products (B). If $Q_c < K_c$, the forward reaction occurs, meaning product concentration increases and reactant concentration decreases, making $Q_c$ rise until $Q_c = K_c$ (C). $Q_c$ is a ratio of concentrations, so its value changes dynamically as the reaction occurs, but evaluating it at a fixed instant doesn't make it inherently 'independent' of temperature if the instant is defined by a physical process (D is false/misleading contextually compared to the nature of $K_c$).
