The equilibrium constant for a reaction ...

The equilibrium constant for a reaction `A+B hArr C+D` is `1xx10^(-2)` at `298 K` and is `2` at `273 K`. The chemical process resulting in the formation of `C` and `D` is

A

Exothermic

B

Endothermic

C

Unpredictable

D

None

Text Solution

Verified by Experts

The correct Answer is:
B
Since K increases on increasing temperature, so the reaction will go forward by increasing temperature and hence is endothermic.
