98. Solving a chemistry problem

1. Gaseous substances A and B react with the formation of a gaseous product C: a) express Kp and Kc in terms of the equilibrium amount of substance C, equal to x, if the starting substances A and B are taken in stoichiometric quantities at a total pressure of the equilibrium system P and temperature T, K ; 2) calculate Kp and Kc at 300 K if P = 7.5* I04 Pa, x = 0.45; 3) calculate the equilibrium amount of substance C at a pressure in the equilibrium system of 3 * 104 Pa and 300 K; 4) calculate the degree of conversion of substances A and B at 300 K
