If the equilibrium concentration of the ...

If the equilibrium concentration of the components in a reaction
`A+B hArr C+D` are 3,5,10 and 15 mol `L^(-1)` respectively then what is `Delta G^(@)` for the reactiona at 300K ?

A

13.81 cal

B

`- 1381.8` cal

C

`-138.18` cal

D

1391.6 cal

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta G= -2.303 RT log K'`, Here R= 2 cal, T = 300K
`K'= (10 xx 15)/(3 xx 5)= 10, Delta G= -2.303 xx 2 xx 300 xx log_(10) 10`
`= -2.303 xx 2 xx 300 xx 1= -1381.8` cal
