Picture (1)represents an equilibrium mixture of solid CaCO 3 ,solid CaO,and gaseous CO 2 ,obtained as a result of the endothermic decomposition of CaCO 3 . 
-Which picture (2)-(4)represents the equilibrium mixture at a higher temperature?

Quizplus · Accepted Answer

Picture (4) likely represents the equilibrium mixture at a higher temperature if it shows an increased concentration of products for an endothermic reaction or decreased concentration of products for an exothermic reaction, according to Le Chatelier's principle. This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change. For an endothermic reaction, increasing the temperature shifts the equilibrium to the right (producing more products), while for an exothermic reaction, it shifts the equilibrium to the left (producing more reactants).
