Answer 1

@rachel.frank40 can you help me with this

Answer 2

can you help me @amorfide

Answer 3

There are many ways to speed up a rate of a reaction!

The temperature is increased. - increasing temperature excites the stuff (particles? atoms? something idk) and makes them move faster, causing a faster reaction

The concentration of a dissolved reactant is increased. - more is better

The pressure of a reacting gas is increased.

Solid reactants are broken into smaller pieces. - easier to work with

A catalyst is used.

so from this information, A is your answer
