Question 1

For the reaction below

CO(g) + 2 H2(g) CH3OH(g)

the equilibrium concentrations at 483 K are [CO] = 0.0753 M, [H2] = 0.151 M, and [CH3OH] = 0.0247 M. Calculate the value of Kc.
◦ 14.4
◦ 1.09
◦ 2.17
◦ 0.0694
◦ 0.917

Question 2

For the reaction CO(g) + 3 H2(g) H2O(g) + CH4(g) , Kc = 190 at 1000 K. If a vessel is filled with these gases such that the initial concentrations are [CO] = 0.025 M, [H2] = 0.045 M, [H2O] = 0.025, M and [CH4] = 0.046 M, in which direction will a reaction occur and why?
◦ toward products because Qc = 0.17
◦ toward reactants because Qc = 0.0029
◦ toward products because Qc = 0.35
◦ toward reactants because Qc = 505
◦ it is at equilibrium because Qc = 1
