Product description

  • Indicate and explain in which direction the equilibrium in the systems will shift:

2СО (g) ⇄ СО2 (g) С (t), ∆H0298= -173.0 kJ

MgCO3(t) ⇄ MgO(t) CO2(g) ∆H0298 = 385.0 kJ

a) when the temperature rises;

b) when the total pressure decreases. Write expressions for the equilibrium constant of these reactions.
