Consider the equilibrium CH₄(g)+ H₂O(g)+ 206 kJ $\leftrightarrows$CO(g)+ 3 H₂(g).Which of the following disturbances will NOT cause the system to shift to the right to reestablish equilibrium?

Quizplus · Accepted Answer

A decrease in the partial pressure of CO (which is a product) or an increase in the partial pressure of CH₄ (which is a reactant) will cause the system to shift to the right to reestablish equilibrium. An increase in temperature will also favor the endothermic direction of the reaction, causing the system to shift to the right. However, a decrease in volume will cause the system to shift to the side with fewer moles of gas, in this case the left side, so it would not favor the formation of products and would not cause the system to shift to the right. Therefore, answer choice C is correct.

Consider the Equilibrium CH4(g)+ H2O(g)+ 206 KJ ⇆\leftrightarrows⇆ CO(g)+ 3 H2(g)

Consider the Equilibrium CH₄(g)+ H₂O(g)+ 206 KJ $\leftrightarrows$ CO(g)+ 3 H₂(g)
