Respuesta :

2. 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:

[tex]k=Ae^{\frac{-E_a}{RT}}[/tex]

k = Rate constant of the reaction at temperature T.

A = frequency factor

[tex]E_a[/tex] = Activation energy.

R = universal gas constant

[tex]k\propto \frac{1}{E_a}[/tex]

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.
