Select the correct definition of activation energy from the list given below:
Group of answer choices
A : The activation energy is the minimum energy required to start a reaction
B : The activation energy is the difference in enthalpy of formation between the products and the reactants
C :The activation energy is a state function that depends only on the state of the reactants and products
D : The activation energy is the maximum energy required to start a reaction
Homework Answers
The correct answer is :
A: Activation energy is the minimum energy required to start a reaction.
Explanation:
During the course of reaction the reactant acquires the activation energy ,which is the optimum energy required for the completion of reaction to form the reaction transition state ,which in turn gives the product.

Identify correct statements pertaining to reaction energies. Group of answer choices The rate of a reaction depends on the energy change between reactants and products. If Keq < 1, the equilibrium will favor the reactants. If ∆G° < 0, Keq will be greater than 1. The reaction step with the highest energy transition state is called the rate determining step.

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the product concentrations rise. At equilibrium concentrations of reactants and products stay constant. At equilibrium there are always equal amounts of reactants and products.
