For an exothermic reaction at equilibrium, raising the temperature:
AShifts equilibrium towards products
BShifts equilibrium towards reactants
CDoes not affect equilibrium
DStops the reaction
Answer & Solution
Correct answer: B. Shifts equilibrium towards reactants
1. Le Chatelier: a system at equilibrium responds to oppose an applied stress.
2. Heating an exothermic reaction adds heat → system absorbs heat by shifting in the ENDOTHERMIC direction (reverse).
3. So equilibrium shifts towards reactants (yield drops with rising T).
