The activation energy for the decomposition of hydrogen iodide is found to be 180 kJ mol–1 and the rate constant for this reaction is reported to be 0.24 mol–1 L min–1at 540 °C. What is k for this reaction at 30 °C?
The uncatalyzed decomposition of CH3CHO has an activation energy of 188 kJ mol-1. I2 catalyzes the reaction, and at 600 K the catalyzed reaction is ten million times faster than the uncatalyzed reaction. Therefore, assuming that the pre-exponential factor, A, is the same for both the uncatalyzed and catalyzed reactions, the activation energy of the catalyzed reaction is, in kJ mol- 80.4 B. 71.0 C. 108 D. 117 E. 172

The activation energy for the isomerization of cyclopropane to propene is 274 kJ/mol. By what factor does the rate of this reaction increase as the temperature rises from 257 to 280 degree C? The factor is the ratio of the rates. Since rate is directly proportional to rate constant, the factor is also ratio of rate constants Make sure your units are correct and cancel properly and use the correct expression: k= Ae^-E_a/RT A catalyst decreases the activation energy of...
