Match the statements given in Column I abd Column II.

Answer

A, B, C, D

Explanation

1. Catalyst alters the rate of reactions by lowering activation energy .
2. Molecularity can't be fraction or zero. If molecularity is zero . If molecularity is zero, then reaction is not possible.
3. Second half -life of first order reactions is same as first beacause half-line time is temperature independent.
4. `e^(-E_(a)//RT)` refers to the fraction of molecules with kinetic energy equal to or greater than activation energy.
5. Energetically favourable reactions are sometime slow due to improper orientation of molecule cause some ineffective collision of molecules.
6. Area under the Maxwell, Boltzmann curve is constant because total probailiy of molecule taking part in a chemical reactions is equal to one.
