Answer to Question #275360 in General Chemistry for boy

Question

2H2 + O2 ⇌ 2H2O

What happens to the reaction when the temperature is decreased? (Which way is the reaction shifted?) and why.

Answer 1

• The reaction shifts to the right.
• More reactants come together to form more product (H2O).

Reason

• This is an exothermic reaction.
• For exothermic reactions, decreasing the temperature will favor a forward reaction while increasing the temperature will favor a backward reaction.
