Options
- AThe rate of reaction
- BThe activation energy
- CThe collision frequency
- DThe fraction of molecules with energies greater than E a
Correct answer
D. The fraction of molecules with energies greater than E a
Step-by-step solution
In the rate expression, e-Ea /RT represents the fraction of molecules with energies equal to or greater than the activation energy E a .
