## Homework Statement

Calculate the equilibrium constant for the reaction forming nitric oxide at room temperature, 25C. G= 1.73x10^5 J/mol, H = 180.5KJ/mol an S = 24.8J/(mol.K)

## Homework Equations

ln K = -G/RT

## The Attempt at a Solution

I subsiuted ln K = (-1.73x10^5) / (8.3145x298.15)

ln K = -69.78

e^-69.78

I'm getting K as 4.95*10^-31

but the computer (where I submit online assignment ) is saying its wrong ... I've only one single attempt left ..can anyone see where I'm wrong.

Thanks and immediate help please!
