The Rate at Which Gas-Phase Hydrogen and Iodine React to Form

question 43

Short Answer

The rate at which gas-phase hydrogen and iodine react to form hydrogen iodide,
H₂(g) +I₂(g) $\rightarrow$ 2 HI(g), can be increased by using a platinum catalyst.Suppose the uncatalyzed reaction has an activation energy of about 180 kJ while that of the catalyzed reaction is about 60 kJ at 600 K.Approximately how many times faster is the catalyzed reaction relative to the uncatalyzed?
Assume the frequency factor is the same for both processes.
