Question

The synthesis of ammonia is given as:
`N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g), DeltaH^(ɵ)=-92.6 kJ mol^(-1)` given `K_(c)=1.2` and temperature `(T)=375^(@)C`
On increasing the temperature, the value of equilibrium constant `K_(c)`
A. Increases
B. Decreases
C. Remain unchanged
D. Cannot be predicted

Answer 1

Correct Answer - B
It is an exothermic reaction. Hence, the value of `K_(c)` decreases with increase in temperature.
