+1995 Which of the following is true of an exothermic reaction?
A) The enthalpy of the products is greater than that of the reactants.
B) The enthalpies of the reactants and the products are equal.
C)The enthalpy of the reactants is greater than that of the products.
i think it is C?
+37146 The ΔH is a positive change in endothermic reactions, and negative in heat-releasing exothermic processes.
ΔH is change in enthalpy = Hf-Hi For this to be NEGATIVE Hi must be greater than Hf so 'C'
+1995 Hi must be greater than Hf ? Do you mean products must be less than products? So C, "The enthalpy of the reactants is greater than that of the products" ?
+37146 Convention dictates the 'i' = iitial 'f' = final in a lot of chemical, physics etc equations
