Transcribed Image Text:Given the same reactant
concentrations, the reaction
CO(g) + Cl₂(g) → COCH₂(g)
at 250°C is 1.50 x 10' times as fast as the same reac-
tion at 150°C. Calculate the activation energy for this
reaction. Assume that the frequency factor is constant.
Expert Solution
Step 1
The relationship between rate constant and temperature is given by Arrhenius equation
k = Ae-Ea/RT
At two different temperatures the above equation can be written as
Ea = Activation energy
R = gas constant = 8.314 J/K.mol
