Acertain rection has equilibrium constant 10 and 100 at 300K and 400K respectively. The ratio of `Delta G^(@)` at 300K and 400K respectively

A

`(1)/(10)`

B

`(3)/(8)`

C

`(1)/(2)`

D

`(3)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
B
`(Delta G_(1)^(@))/(Delta G_(2)^(@))=(-2.303 RT_(1) log K_(P_(1)))/(-2.303 RT_(2) log K_(P_(2)))=(T_(1))/(T_(2)) xx (log K_(P_(1)))/(log K_(P_(2)))=(300)/(400) xx (log^(10))/(log^(100))=(3)/(8)`
