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

there is no relationship between `K` and `DeltaH`

Text Solution

Verified by Experts

`K_(c)` increase with temperature and thus reaction is endothermic.
