Estimate the free energy change (ΔGrxn) for the following reaction at 298 K, if each gaseous substance is present at p = 0.40 atm.
N2(g) + 3H2(g) ? 2NH3(g)Enter your answer in kJ.
I know you have to calculate the Delta G first and then use the equation Delta G= Delta_o+RT ln(Q) but I am unsure how to get Q and how the atm is included.
