Under certain conditions, gaseous ammonia can decompose into nitrogen and hydrogen gases: The partial pressures of , , and are denoted , , and respectively. When the initial partial pressure of each gas is equal to the standard value of 1.00 atm and the temperature is fixed at 298 K, the change in Gibbs free energy for the reaction, , is 33.00 kJ/mol. Calculate, to 3 significant figures, the change in Gibbs free energy, , at 298 K when , , and .
Which of the following is the best definition of , the standard change in Gibbs free energy for a reversible process?
The standard change in Gibbs free energy for a reversible process, , is measured for a standard solution of reactants and products. What are the initial concentrations of the reactants and products in this solution?
