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?
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'
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" ?
