Answer is: True.
For example chemical
reaction: NH₄⁺ + OH⁻ ⇄ NH₃ + H₂O ΔH>0 or
heat + NH₄⁺ + OH⁻ ⇄ NH₃ + H₂O.
This is endothermic reaction.
According to Le Chatelier's Principle, the
position of equilibrium moves to counteract the change, because heat is
increased, system consume that heat, so equilibrium is shifted to right,
by decreasing concentration of reactants and increasing concentration of
product.
