how does increasing reactants concentrations increase the rate of a reaction?\nincreasing the frequency of collisions\nincreasing the frequency of collisions and the proportion of molecules with sufficient energy, the $e_a$\nlowering the $e_a$\nlowering the $delta h$
Answer
Brief Explanations:
Increasing reactant concentrations means more reactant particles in a given volume. This leads to a higher frequency of collisions between particles, which is necessary for a reaction to occur. Changing reactant concentration does not affect the proportion of molecules with sufficient energy (activation energy $E_a$) or $E_a$ itself or $\Delta H$.
Answer:
Increasing the frequency of collisions
