Question

Explain why each change in conditions would affect the reaction rate of reaction when sodium metal reacts with chlorine gas to form NaCl?

As a catalyst is added to the mixture the reaction rate will increase because
As temperature decreases the reaction rate will decrease because
As volume decreases the reaction rate will increase because
As concentration increases the reaction rate will increase because
As the surface area of a molecule is decreased the reaction rate will decrease because
As pressure increases the reaction rate will increase because

Options for each one above, pick one option for each above:

more collisions occur between the atoms

fewer collisions occur between the atoms

more collisions and more energy occur between the atoms

fewer collisions and less energy occur between the atoms

reduces the activation energy needed

increases the activation energy needed
