Question

In the equilibrium system below, which of the following changes would cause the equilibrium position to shift to the right? CO(g) + 3H2 (g) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. CH4 (g) + H2O (g) delta H = -206 kJ/mol c
decreasing the concentration of carbon monoxide (CO)
increasing the volume of the reaction system
decreasing the concentration of hydrogen gas (H2)
lowering the temperature of the reaction

Answer 1

We are given with the equation that produces methane and water from the raection of hydrogen gas and carbon monoxide. This is expressed in the balanced equation: 3H2 + CO = CH4 + H2O. This is an exothermic process. The change that would shift the equilibrium to the right is lowering the temperature of the reaction.
