For the chemical reaction X Y , the standard reaction Gibbs energy depends on temperature T (in K) as `Delta_rG^0` ( in kJ `mol^(-1)` ) = `120-3/8`T . The major component of the reaction mixture at T is

A

Y if T = 280K

B

Y if T = 300 K

C

X if T = 315K

D

X if T = 350K

Text Solution

Verified by Experts

The correct Answer is:
C
At `315 K Delta G^(@) = 120 - (3)/(8) xx 315`
`Delta G^(@) = 1.875`
Amount of Y will be greater than its equilibrium amount at 315 K .
