Answer 2

Answer:1). Temperature

2) catalyst

3) heat/ temperature

4). Concentration

Explanation:1) A reaction becomes slower when the temperature is decreased.

2) A catalyst increases the rate of reaction but remains chemically unchanged itself.

3) The heat produces steam as well as temperature increases the rate.

4) The rate of a reaction depends on the concentration of a reactant.
