EASY QUICK CHEM QUESTION!! Which line indicates a higher reaction rate?

  1. A because it has a lower activation energy.
  2. B because it has a lower activation energy.
  3. A because its ΔGrxn is much lower.
  4. B because its ΔGrxn is much lower.

Verified Answer :

  1. B because it has a lower activation energy.

    idk because you have no picture with the lines on it

Answer:The correct answer si option B.

Explanation:

According to Arrhenius equation:

\(k=Ae^{\frac{-E_a}{RT}}\)

k = Rate constant of the reaction at temperature T.

A = frequency factor

\(E_a\) = Activation energy.

R = universal gas constant

\(k\propto \frac{1}{E_a}\)

The graph clearly tells us that the activation energy of the reaction A is more than the reaction B.

This means that rate constant of the reaction A is smaller than the rate constant of the reaction B according Arrhenius equation.

As we know  that higher the value of rate constant more will be the rate of the reaction.Then the rate of reaction B is more than that of the rate of reaction A.

Hence, the the correct answer is option B.
