WebAn exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”. … WebThis can be seen on the graph, as the slope becomes less steep and then levels out when the reaction has stopped (when no more gas is produced). The reaction is exothermic, but the dilute acid is in excess and the rise in temperature is only of the order of 3.5˚C. There is some acceleration of the reaction rate due to the rise in temperature.
