Question

When the temperature of an endothermic reaction at equilibrium is increased .

a)The equilibrium is not changed

b)The equilibrium shifts to the RHS

c)none of these

d)The equilibrium shifts to the LHS

Answer 1

During an endothermic reaction, heat is absorbed and we can picture heat as being a reactant on the left-hand side of the equation. Increasing temperature is like increasing the amount of reactants so by Le Chatelier's principle, equilibrium will favor the products. Therefore, the answer is b) the equilibrium shifts to the RHS.
