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.
At constant pressure, the heat flow for the process is also equal to the change in enthalpy. Heat flow is expressed as q.. The relationship between Delta H and q can be determined based on whether the reaction is exothermic or endothermic. If the reaction absorbs heat from the surroundings, it is endothermic, and q is positive. If q is positive, then Delta H is also positive. If the reaction releases heat to its surroundings, it is exothermic, and q is negative. If q is negative, then Delta H is also negative.
