Question

What is the lowest possible activation energy for an endothermic reaction?

Answer 1

Answer:

For endothermic reaction minimum value of activation energy

What is the minimum possible value of activation energy for exothermic and endothermic reactions? Activation energy is the minimum amount of energy that is needed to start a chemical reaction. ΔH is found by subtracting the energy of the reactants from the energy of the products.J

Answer 2

Activation energy is the minimum amount of energy that is needed to start a chemical reaction. ΔH is found by subtracting the energy of the reactants from the energy of the products. We find the energy of the reactants and the products from the graph.

ΔH = Energy of products − Energy of reactants

ΔH < 0 for exothermic reaction and ΔH > 0 for endothermic reaction

Activation energy, Ea = Energy of activated complex − Energy of reactants
