Question

Methanol can be synthesized by combining carbon monoxide and hydrogen. co( g) + 2h 2( g) ch 3oh( g) δ h° rxn = –90.7 kj a reaction vessel contains these compounds at equilibrium. what effect will be seen when equilibrium is re-established after decreasing the temperature by 45°c?

Answer 1

Answer:- More methanol is produced.

Explanations:- From Le Chatelier's principle,"If a change is made at equilibrium then the reaction shifts to the direction in which the change is canceled."

For example, if the temperature is increased then reaction moves to the direction where the heat is consumed means the increase in temperature favors endothermic reaction.

The given reaction is exothermic in nature. So, the decrease in temperature favors the forward reaction and the production of methanol is increases.
