The following reaction is performed at 298 K.
`2NO(g)` +` O_2(g)` `rarr` `2NO_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`=`1.6 xx 10^(12)`)

A

`86600+R(298) ln(1.6 xx 10^12`)

B

86600 - `(ln(1.6xx 10^(12))/(R(298)))`

C

`0.5[2 xx 86,600-R(298) ln (1.6 xx 10^(12)]`
