Question

2. What would be the effect of each of the following on the equilibrium involving the synthesis of methanol? CO(g) + 2H2(g) ↔ CH3OH(g)

a.) The removal of CH3OH?

b.) An increase in pressure?

c.) Lowering the concentration of H2?

d.) The addition of a catalyst?

Answer 1

CO(g) + 2H2(g) ↔ CH3OH(g)

a.) The removal of CH3OH

concentraction of reactants increases Or concentraction of products decreases to favor far ward reaction

the removal of CH3OH . so concentraction of products decreases reaction favor far ward direction.

b.) An increase in pressure

When pressure increases volume or no of moles decreases side favor reaction

So pressure increses no of moles decreases side means formation of Ch3OH favors

c.) Lowering the concentration of H2

Concentraction of reactants decreases reaction favor back ward direction

So concentraction of H2 decreases reaction favor back ward direction

d.) The addition of a catalyst

catalyst increases the rate of far ward reaction and rate of back ward reaction. But euilibrium form small intraval of time
