Q.N0-19. The given reaction is C2H2(g) + H2(g) ----------> C2H4(g)
s0rxn
= S0 products - s0 reactants
= S0 C2H4(g) - s0 C2H2(g) - s0
H2(g)
= 219.4 -200.8-130.58
= -111.98 -112 J/K-mole
Q.N0-24. Thermodynamics does not give information about the speed of a reaction but it gives information about the spontaneity of a reaction, direction of spontaneous reaction and extent of reaction and the value of equilibrium constant and the temperature at which reaction is spontaneous.
If G = -ve, the reaction is spontaneous reaction and the free energy and equilibrium constant related by G = -RTlnK
