61. Solving a chemistry problem

2) The process is represented by the equation: С2Н4(g) Н2О(l)↔ С2Н5ОН(l);ΔН > 0. Write the expressions: - for the rate of the direct reaction; - for the rate of the reverse reaction; - for the chemical equilibrium constant. Where does the equilibrium shift with a) an increase in pressure in the system; b) when the temperature rises; c) when the concentration of C2H4 decreases?
