WebJan 30, 2024 · An exothermic reaction occurs when the temperature of a system increases due to the evolution of heat. This heat is released into the surroundings, resulting in an overall negative quantity for the heat of reaction ( qrxn < 0 ). WebFeb 7, 2024 · Re: ∆H vs ∆Hrxn. Usually, it is safe to assume that delta H and delta Hrxn are the same. But it is still important to pay attention to the subscript. For example, using the enthaply equation q (sys) = -q (surr), the subscripts would change if the value is positive or negative. Relating it back to delta Hrxn, this would be q (sys).
