AT673 K. in the formation of `NH_(3)` From `N_(2) and H_(2)` , the partial pressures of `N_(2) , H_(2) and and NH_(3)` at equilibrium are 0.5 , 1 and `9 xx 10^(-3) ` atm respectively. `(N_(2) + 3H_(2) hArr + Q)`
Report `Delta G^(@)` using `K_(p)` value

A

22.66 kcal

B

11.33 kcal

C

61.33 kcal

D

30.2 kcal

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta G^(@)= -2.303 RT log K_(P)`
`=2.303 xx 2 xx 10^(-3) xx 673 log 2 xx 81 xx 10^(-6)`
= 11.3 K.cal
