Consider the energy diagram below. Which line indicates a higher reaction rate?
A because it has a lower activation energy.
B because it has a lower activation energy.
A because its (angle)Grxn is much lower.
B because its (angle)Grxn is much lower.

B because it has a lower activation energy

Answer is to avoid experimental error

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
