Answer:
increasing the number of molecules that have sufficient kinetic energy to react.
Explanation:
An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react.
or we say; temperature increase, leads to an increase in the amount of collisions between molecules.

Ca (Clo3)2(s) ⇒ Ca Cl2 (s) + 3 O2 (g)
Thomson concluded that electrons must be parts of the atoms of all elements. Millikan determined the charge and mass of the electron. What experimental evidence led Rutherford to conclude that an atom is mostly empty space? The majority of the alpha particles passed straight through the gold foil.
