Question 1
Consider a reaction where the rate is found to be dependent on two reactants, A and B. If the reaction is zero order with respect to A and first order with respect to B, how does doubling [B] affect the rate?
💡 Hint: Focus on the definition of reaction order.
Question 2
A student measures the rate at different temperatures and finds that at 300 K, k = 1.00 × 10^-3 s^-1, and at 310 K, k = 3.00 × 10^-3 s^-1. Determine the activation energy using the Arrhenius equation.
💡 Hint: Think about how to isolate Ea using the given temperatures and rate constants.
