General Chemistry Exam - Flashcards

For the reaction $2A(g) \rightleftharpoons B(g) + C(g)$, at a certain temperature, $K = 4$. If the initial partial pressures are $P_A = 2 \text{ atm}$, $P_B = 1 \text{ atm}$, and $P_C = 1 \text{ atm}$, calculate the reaction quotient, $Q$.

If a reaction has a very high activation energy, $E_a$, how will this affect the rate of the reaction?

Explain how a catalyst affects the activation energy and the rate of a reaction.
