WebThus, r H° = f H°gypsum - f H°anhydrite - f H°water = -16.86 kJ/mol. ; Exothermic vs. Endothermic If r H° < 0 the reaction produces a reduction in enthalpy and is exothermic (heat is given up by the rock and gained by … WebReactions can either release or absorb energy in the form of heat; Endothermic reactions absorb heat while exothermic reactions release heat. The absorption and release of heat can be represented quantitatively by enthalpy (H), which equates to the heat content of a system. A positive +ΔH value results in a gain of heat in a system, which ...
WebExplanation: X → Y and Y → Z In the process of Y → Z, heat flows into the system so q > 0. In the process of X → Y, the gas is expanding, it is doing work on the system so q > 0. In the process Z → X, heat is flowing out of the system so q < 0. A) A function that depends on what route is taken between start and finish.
