An industrial chemist investigates the decomposition of hydrogen peroxide using a solid manganese(IV) oxide catalyst.
They compare using a single large spherical pellet of manganese(IV) oxide to using the same mass of manganese(IV) oxide as a fine powder. All other conditions are kept constant.
Explain, in terms of collision theory, the effect on the rate of reaction when using the fine powder.
