which line indicates a higher reaction rate?\na because it has a lower activation energy.\nb because it has a lower activation energy.\na because its $delta g_{rxn}$ is much lower.\nb because its $delta g_{rxn}$ is much lower.

which line indicates a higher reaction rate?\na because it has a lower activation energy.\nb because it has a lower activation energy.\na because its $delta g_{rxn}$ is much lower.\nb because its $delta g_{rxn}$ is much lower.

Answer

Brief Explanations:

The reaction rate is related to activation energy. A lower - activation - energy reaction proceeds faster. In the graph, line B has a lower peak (activation energy) compared to line A. $\Delta G_{rxn}$ (Gibbs free energy change of the reaction) is related to the spontaneity and equilibrium of the reaction, not the reaction rate.

Answer:

B because it has a lower activation energy.
