Is exo negative
WebDec 4, 2016 · Explanation: When the value of ΔH is negative, the system has released energy into the universe. The system would be a exothermic one. Consider the graphic below: As … WebExothermic vs. Endothermic Reaction. For reactions in which there is an increase in the kinetic energy of the products, Q is positive. The positive Q reactions are said to be exothermic (or exergic ). There is a net release of energy since the kinetic energy of the final state is greater than the kinetic energy of the initial state.
