# What is the enthalpy of reaction from the following energy diagram [Solved] Whats the enthalpy of response from the next power diagram

A. -20kj Clarification: The response is exothermic due to this fact enthalpy = 20 40 = -20

Reply : The proper possibility is, (a) -20 kJ Clarification : Endothermic response : Its outlined because the chemical response by which the power is absorbed from the encircling. Within the endothermic response, the power of reactant are lower than the power of product. Exothermic response : Its outlined because the chemical response by which the power is launched into the encircling. Within the exothermic response, the power of reactant are greater than the power of product. Enthalpy change : Its the distinction between the power of product and the reactant. Its represented as . In an endothermic response, the power of merchandise are increased than the reactants power. Thus, the change in enthalpy is optimistic. In an exothermic response, the power of merchandise are lesser than the reactants power. Thus, the change in enthalpy is damaging. From the given power diagram we conclude that that is an exothermic response diagram. Thus, the enthalpy of response is, -20 kJ

from the graph, h(c d) = 20 and h(a b) = 40. substituting the identified values, h = 20 kj 40 kj h = -20 kj thus, the reply to this merchandise is letter a.
