Question

For an endothermic reaction, energy of
activation is E, and enthalpy of reaction is
Delta H (both of these in kJ/mol). Minimum
value of E, will be
(a) less than DeltaH (b) equal to Delta H
(c) more than Delta H (d) equal to zero

Answer 1

Answer:

(c). More than delta H

Explanation:

In endothermic reactions ,energy of reactants is less than that of the products,

where Ea= activation energy of forwarding reaction

Ea'=activation energy of backwards reaction

deltaH= enthalpy of the reaction

Ea=Ea'+deltaH

thus Ea>deltaH
