74. Solving a chemistry problem

15. A heterogeneous reaction proceeds at a constant temperature T:
1. determine the normal affinity of substances A and B at temperature T.
2. Calculate the equilibrium constants Kp and Kc of the reaction at temperature T.
3. determine the amount of reacted solid A (taken in excess) if the volume of the system is Vm3, and the initial gas pressure B is equal to p1 (the volume of the solid phase can be neglected).
4. determine the change in the isobaric-isothermal potential related to the beginning of the reaction, if the initial pressures of gaseous substances B and C, respectively, are equal to p2 and p3, and the reaction proceeds at a temperature T.
