1. The problem statement, all variables and given/known data 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) 2. Relevant equations ln K = -G/RT 3. 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!
