calculate the following quantities for mixing 5 mol of h2 with 3 mol of o2 at 300 k and 1 atm under conditions where no chemical reaction occurs, assuming ideal gases: change in gibbs free energy for the system, change in helmholtz free energy for the system, change in entropy for the system, and change in chemical potential for h2. change in enthalpy for h2. change in energy for h2. is the process spontaneous? why?
