Question 27
27.

Measuring the gas produced, the mass lost, or the light transmitted are all ways of measuring the rate of reaction.

Question 28
28.

Describe to Jun a method he could use to measure rate of reaction, and an advantage of using this method.

Question 29
29.

Increasing the pressure of gases in a reaction will increase the rate of reaction.

Question 30
30.

Increasing the temperature of reactants increases the number of particles in the reaction.

Question 31
31.

There are five main factors that affect the rate of reaction.

Question 32
32.

For every 10°C temperature increase, the rate of reaction triples.

Question 33
33.

Collision theory states that particles must collide with enough energy in order to react.

Question 34
34.

The minimum amount of energy required for a successful collision is called the starter energy.
