Question

Outline in which direction the equilibrium 2 points

will shift in response to an increase in pressure:
CO(g) + 2H2 = CH3OH(9)
​

Answer 1

Step-by-step explanation:

Reaction equation:

CO + 2H₂ → CH₃OH

All the species are in gaseous state and the equation is balanced.

Change in pressure only affects equilibrium involving a gas or gases.

Based on Le Chatelier's principle, an increase in pressure will shift the position of equilibrium to the side having smaller volume or number of moles and vice versa.

CO + 2H₂ → CH₃OH

3moles of gases 1 mole of gas

An increase in pressure favors the forward reaction. A decrease in pressure will favor the backward step.
