95. Solving a chemistry problem

A heterogeneous reaction proceeds at a constant temperature
T= 700 K
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 equal to 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 are equal to p2 and p3, respectively, and the reaction proceeds at a temperature T.
5. How does pressure affect the equilibrium yield of reaction products?
Reaction: C 2H2 = CH4
Р1= 700*10-2 N/m2
Р2= 84*10-2 N/m2
Р3= 50*10-2 N/m2
V*10-3, m3= 10
