Practice Questions

Question 1

Which of the following conditions must be met for a chemical reaction to be at equilibrium?

Question 2

How is the standard Gibbs free energy change ($\Delta G^⊚$) related to the equilibrium constant ($K$) at a given temperature ($T$)?

Question 3

For an endothermic reaction, what happens to the equilibrium constant ($K$) when the temperature is increased?

Question 4

Consider the reaction: $A(g) + B(g) \rightleftharpoons C(g)$. If the equilibrium constant ($K_p$) is 4.0 at a certain temperature, and the partial pressures of A, B, and C are $P_A = 0.5 \text{ atm}$, $P_B = 0.5 \text{ atm}$, and $P_C = 1.0 \text{ atm}$ respectively, what is the reaction quotient ($Q_p$)?

Question 5
