How does an increase in concentration affect a chemical reaction? (3 points)

When temperature increases, what happens to the molecules in a chemical reaction? (4 points)

How do we measure the average kinetic motion of molecules in a solution? (3 points)

Explanation:

1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.

2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.

3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.

the answer is a and have a great day
