free energy chemistry
I need help with a free energy chemistry question?
I need help with this problem:
Solid sodium bicarbonate, NaHCO3, is heated to 90C. At equilibrium the total pressure of the gases produced is 0.735atm. Calculate the change in Free Energy for the following reaction:
2NaHCO3 9(s) <--> Na2CO3(s) + H2O(g) + CO2(g)
First you will need the enthalpy of formation for each step of the reaction, once you have it, you must calculate the change in energy by subtracting the total of those numbers from the total amount of energy stored in the compounds taking into account the temperature and pressure at equilibrium.
