Web7 mrt. 2024 · A reaction is endothermic if and only if $\Delta H$ is positive. $\Delta G$ has nothing to do here. It can be positive or negative. If $\Delta G$ is positive, the reaction is endoergic ! $\endgroup$ – Maurice. Mar 7, 2024 at 12:36 $\begingroup$ @Maurice this is what I was thinking too.

Web18 mrt. 2024 · ΔH = dq. So , if ΔH is positive, energy is given to the system from the surrounding in the form of heat. For example if we supply 36 kJ of energy through an electric heater immersed in an open beaker of water, … Web∆ H is positive: the products have a higher energy level than the reactants and the reaction was endothermic, absorbing net heat. ∆ H is negative: the products have less energy than the reactants. An exothermic reaction produced net heat. Hence, ∆ H is both negative and positive. Suggest Corrections 0 Similar questions Q. changer mot de passe outlook application
