77. Solving a chemistry problem

67. Using tabular data, calculate ΔН ° 298 and, taking into account the sign (ΔН ° 298) x.r, determine how the temperature increase will affect the equilibrium position. In what direction will the equilibrium shift if at T=const
increase external pressure?
e) C2H4(r) ↔ C2H2(g) H2(g)
f) 2С(gr) H2(g) ↔ С2H2(g)
