All
questions are true or false
A catalyst changes both the equilibrium constant and the rate of a chemical equilibrium. j. Ifthe temperature of a chemical equilibrium is increased, the reaction will shift in a direction that will lead to the consumption of some of the extra heat. An increase in temperature favors an endothermic reaction over an exothermic reaction. k. nundifis Is ined If a chemical equilibrium is exothermic in the forward direction, it is also exothermic in the...
