Transition state theory gives the rate constant as__________________?
Correct answer: C. K α T . e-E/RT
- A. K α e-E/RT
- B. K α eE/RT
- C. K α T . e-E/RT
- D. K α √T . e-E/RT
Explanation
Transition state theory includes a frequency term proportional to temperature, giving k proportional to T exp(-E/RT) in the simplified form. The exponential term represents the fraction of molecules able to cross the activation barrier.
