In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
Best Answer: exothermic: 1. release heat, therefore the room temperature will increase 2. ÎH = negative (kJ mol^-1) 3. bond will be formed, and energy will be release in form of heat, the molecules that are formed had a lower kinetic energy but very stabil endothermic: 1. absorb heat, therefore the room temperature will decrease 2. ÎH = positive (kJ mol^-1) 3. bonds will broke down, because the energy of reactants are less than the energy of products in the chemical reaction
