What are four factors which affect the rate of chemical reaction?

Answer 1

Temperature, atmospheric pressure (normal circumstances would be 1atm), percentage uncertainty of the equipment, loss of heat to your surroundings, parallax when reading scales such as a thermometer. And basically any variables that can be changed to be more accurate e.g your using cm's instead of mm's.

Hope that helps :)

Answer 2

the four factors that affect a chemical reaction are

Temperature

concentration of reactants

nature of reactants and

presence of catalyst

Answer 3

There are four main factors that affect how rapidly a chemical reaction takes place. These are the concentration of reactants, degree of subdivision, temperature and presence of a catalyst.

Answer 4

High temperature, Surface area, concentration of the liquid, type of element compound or mixture

Answer 5

1. Temperature

2. Concentration of reactants

3. Particle Size/Surface Area

4. Presence (or absence) of a catalyst.

I just took a test on that today! :]

Answer 6

concentration of the reactants

surface area of the reactants

presence or absence of a catalyst

temperature

Answer 7

Four factors are:
- temperature
- pressure
- catalysts
- stirring

Answer 8

Amount, temperature, pressure, state.
