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.

Catalysts speed up the rate of a reaction they are not involved in the reaction. Nacl Doesnt require higher concentration for any reaction to occur because if you construct a balanced equation you would realise that ratio of mole are equal. so i go with more concentrated solution particles of reactants collide more frequently
