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.

Answer 1

2. B because it has a lower activation energy.

idk because you have no picture with the lines on it

Answer 2

Answer:The correct answer si option B.

Step-by-step explanation:

According to Arrhenius equation:

`k=Ae^{(-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 (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.
