Rate Of Reaction

Question 1

Word equation

Answer 1

Mean rate of reaction:

Quantity of reactant used / time

Question 2

Measuring the rate of reaction:

Answer 2

Decreasing mass of the reaction mixture

Increasing volume of had given off

Decreasing light passing through a solution

Question 3

Line on graph:

Answer 3

Steeper the line, faster the rate of reaction

Question 4

Collision:

Answer 4

All only some collisions lead to reactions

Increasing number of collisions , the energy will produces faster of rate of reaction

A large surface area does not result in collisions with more energy.
But does increases the number of frequency of collisions

Question 5

Activation energy:

Answer 5

The minimum amount of energy that particles must have before they can react.
What
