Question

State any four factors affect the speed (or rate) of a reaction​

Answer 1

Answer:

1.The concentration of the reactants. The more concentrated the faster the rate.

2.Temperature. Usually reactions speed up with increasing temperature.

3.Physical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate.

4.The presence (and concentration/physical form) of a catalyst (or inhibitor). A catalyst speeds up a reaction, an inhibitor slows it down.

5.Light. Light of a particular wavelength may also speed up a reaction
