Assertion: A reaction `2SO_(2)+O_(2)hArr2SO_(3)` , has `K_(p)` at 298 K and 500 K as `4.0xx10^(24` and `8.5xx10^(10)` respectively.
Reason: The `E_(a)` for the forward reaction is lesser than `E_(b)` for the backward reaction.

A

(a)If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

(b)If both assertion and reason are true and the reason is not the correct explanation of the assertion.

C

(c )If assertion is true but reason is false.

D

(d)If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(p)` decreases with temperature and thus, `DeltaH= -ve`. Also, `DeltaH=E_(a)(f)-E_(a)(b)`. The negative value of `DeltaH` is possible only when `E_(a)(b)gt E_(a)(f)`.
