For the given process A gas mixture reacts exothermically at a fixed volume. ΔH is less than ΔE.
H = U + PV The enthalpy of a closed homogeneous system is its energy function H, ∆H is the exchange in enthalpy from reactants to merchandise
∆H is the exchange in enthalpy from reactants to merchandise A ΔHº fee represents an addition of power from the reaction and from the environment, resulting in an endothermic response. A terrible cost for ΔHº represents the removal of electricity from the reaction and into the surroundings and so the response is exothermic.
The full enthalpy of a machine cannot be measured without delay due to the fact the inner strength includes additives that are unknown, now not effortlessly on hand, or aren't of interest in thermodynamics.
