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

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.

The rate of reaction is said to increase when the vinegar is heated and the collisions increase.

What is 'rate of reaction'?

The term rate of reaction refers to how fast or slow that a reaction occurs. The collision theory states that reactions occur when molecules collide with each other.

Now we know that the kinetic energy of molecules increase when they heated hence they collide more frequently when the temperature is raised and the rate of reaction incresaes.
