According to the collision theory which of the following changes would increase the rate of a reaction between vinegar and sodium hydroxide

Increase the concentrations,

Decrease the surface area of NaOH (in case it's solid);

Use a catalyst;

Increase the temperature

Explanation:

Reaction rate depends on:

the concentration of the reactants: the greater the concentration, the greater the rate, since more particles per unit volume will increase the probability of a successful collision leading to a reaction. We may then increase the concentration of NaOH or vinegar solution;the surface area of the solid reactant: in case we have NaOH in solid form, we may decrease the size of the crystals to increase the reaction rate. This is because the greater the area, the more particles are likely to collide with it;add a catalyst: catalysts increase reaction rate, in this problem, we don't need any catalyst, as this is an acid-base reaction that is relatively quick, a catalyst would decrease the activation energy barrier;increase the temperature: higher energy of the particles and a higher velocity of each reactant would increase the probability of a successful collision.
