For the reaction CO2(g) + H2(g) = CO(g) + H2O(g)
the equilibrium constant at 1000 K is 0.53.
(a) If a mixture at equilibrium in a 1 dm3 vessel contains 0.25 mole of CO and 0.6 mole of H2, how
many moles of H2O are there in the vessel?
(b) 5 moles of inert gas are added to the equilibrium mixture containing 1 mole of H2 and 1 mole of CO2
in 1 dm3 vessel. Predict equilibrium concentration of CO2 and H2O.

Define the basic terms-isolated system, state function, energy, heat, enthalpy

Suppose that 2.0 mol H2 at 2.0 ATM and 25*C and 4.0 mol N2 at 3.0 atm and 25*C are mixed at constant volume. Calculate delta mix G. What would be the value of delta mix G had the pressure been identical initially

Calculate the change of Gibbs energy when 3.0 mol H2 mixes with 1.0 mol N2 at the same pressure with the volume of the vessel adjusted accordingly.
