Consider thereaction 2NO2(g)?N2O4(g).

Using the following data, calculate ?G? at298 K. ?G?(NO2(g)) =51.84 kJ/mol, ?G?(N2O4(g)) =98.28 kJ/mol.

I answered part A but need help with B. Part A is-5.40kJ

Part B

Calculate ?G at298 K ifthe partial pressures of NO2 and N2O4 are0.37 atm and1.60 atm ,respectively.

Express your answer using one significant figure.

Thank you.
