Catalyst Effect on Activation Energy
Manganese dioxide acts as a catalyst in the decomposition of hydrogen peroxide. How does it affect this reaction?
A
It changes the decomposition from exothermic to endothermic.
B
It allows the decomposition to occur without any activation energy.
C
It decreases the activation energy required for the decomposition to proceed.
D
It increases the activation energy required for the decomposition to proceed.
