The following reaction is performed at 298 K ?
`2NO(g)+O_(2)(g)hArr2NO_(2)(g)`
The standard free energy of formation of NO(g) is 86.6 kJ/mol at 298 K. What is the standard free energy of formation of `NO_(2)(g)` at 298 K ?
`(K_(p)=1.6xx10^(12))`

Options

A. `R(298) ln (1.6 xx 10^(12))-86600`
B. `86600 =R(298) ln (1.6 xx 10^(12))`
C. `86600-(ln (1.6 xx 10^(12)))/(R(298))`
D. `0.5 [2 xx 86600 -R(298)ln (1.6 xx 10^(12))]`

Answer

D
