74. Solving a chemistry problem

1. Gaseous substances A and B react according to a given reaction equation to form gaseous substance C.
1. Express Kp and Ks in terms of the equilibrium amount of substance C, equal to x if the initial substances A and B are taken in stoichiometric quantities at an equilibrium pressure in the system equal to P, Pa and temperature T, K.
2. Calculate the values of Kp and Ks at T = 300 K, if P = 7.5*104 N/m2, x = 0.45.
3. Calculate the equilibrium amount of substance C at a pressure in the system of 3*104 N/m2 and 300K;
4. Calculate the degree of conversion of substances A and B at 300K
