Detailed explanation-1: -When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing a thermometer in the reaction mixture.

Detailed explanation-2: -Assertion :The endothermic reactions are favoured at lower temperature and the exothermic reactions are favoured at higher temperature. Reason: When a system in equilibrium is disturbed by changing the temperature, it will tend to adjust itself so as to overcome the effect of the change.

Detailed explanation-3: -Answer and Explanation: In exothermic reaction the temperature increases when the particle undergo chemical reactions, The temperature decreases, when the particles are kept in the surrounding that is the heat is released in the surrounding.

Detailed explanation-4: -An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
