Question

A student performs the reaction shown below.
NaOH + HCl → NaCl + H2O
She increases the concentrations of NaOH and HCl, and finds that NaCl is produced much more quickly. Which explains the outcome of her experiment?

NaOH and HCl molecules collide more frequently at higher concentrations.
NaCl requires a high concentration for any reaction to occur.
HCl acts as a catalyst, but only at high concentrations.
The higher concentrations create a higher temperature in the solution.
