Question

Catalysts X and Y lower E_a of a reaction from 90 to 60 and 70 kJ mol^-1 respectively, with equal pre-exponential factors. Take R = 8.314 J mol^-1K^-1. Select all correct statements.

Accepted Answer

At 298 K, k_X/k_uncat exceeds 10^5.

Accepted Answer

At 298 K, k_X/k_Y lies between 50 and 60.

Answer

At 298 K, k_X/k_Y is about 10.

Answer

k_X/k_Y increases when the temperature is raised.

Catalysts X and Y lower $E_{a}$ of a reaction from $90$ to $60$ and $70 kJ mo l^{- 1}$ respectively, with equal pre-exponential factors. Take $R = 8.314 J mo l^{- 1} K^{- 1}$ . Select all correct statements.
