Question

Two reactions $A 	o products$ and $B 	o products$ have rate constants ${K_A}$ and ${K_B}$ at temperature $T$ and activation energies ${E_A}$ and ${E_B}$ respectively. If ${K_A} > {K_B}$ and ${E_A} < {E_B}$ and assuming that $A$ for both the reactions is same, then:

Accepted Answer

All of the above

Answer

At higher temperatures ${K_A}$ will be greater than ${K_B}$

Answer

At lower temperature ${K_A}$ and ${K_B}$ will differ more and ${K_A} > {K_B}$

Answer

As temperature rises ${K_A}$ and ${K_B}$ will be close to each other in magnitude
