For the gaseous phase reaction 2NO hArr ...

For the gaseous phase reaction `2NO hArr N_2 +O_2 DeltaH^(@) =+ 43.5 "kcal mol"^(-1)` Which statement is correct

A

K varies with addition of NO

B

K decrease as temperature decreases

C

K Increases as temperature decreases

D

K is independent of temperature

Text Solution

Verified by Experts

The correct Answer is:
B
`2.303 log""(K_2)/(K_1)=(DeltaH)/R([T_2-T_1])/(T_1 xxT_2)`
`DeltaH =` +ve for the reaction.
