Find the partial pressures of each of the gases (HCI, H2, and Cl) at equilibrium, in terms of the extent (which we will denote by a) of the reaction and the total pressure P of the system. Assume we start with just 2 moles of hydrogen chloride, and then wait for the reaction to come (b) Write an expression for the equilibrium constant K of the reaction, assuming some reference pressure P°. Assuming the actual pressure is equal to the reference pressure which is equal to 1 bar, and a = 1.0 x 10°, calculate K. (c) Find the reaction's standard Gibbs free energy (AG°) at a temperature of 900 K.
