For an exothermic reaction that is at equilibrium at 40C wha

For an exothermic reaction that is at equilibrium at 40°C, what will happen to the equilibrium if the temperature is changed to 400 K? Choose one: O The equilibrium will shift to the reactants because the temperature increased. The equilibrium will shift to the products because the temperature decreased. O The equilibrium will shift to the products because the temperature increased. The equilibrium will shift to the reactants because the temperature decreased.

Solution

In the given question the temperature of the reaction is increasing (from 313K to 400K).

let\'s take an example of exothermic reaction ,

CaO_(s) + H₂O_(l) = Ca(OH)_2(s) + heat

If we raising the temperature of the reaction it favours the REVERSE REACTION.

means, it take the reaction towards the left side (reactant side).
