When NH3 combines with O2 to make N2 and H2O, the coefficient for NH3 in the balanced rxn is
CH3CH2OH + 3 O2 --> 2 CO2 + 3 H2O
MnO2 is a catalyst
A + B <--> AB
a decrease in total pressure

H2O2, hydrogen peroxide, decomposes to H2O and O2. If you add MnO2, the activation energy decreases and reaction rate increases. Why?
CH3CH2OH + 3 O2 --> 2 CO2 + 3 H2O
MnO2 is a catalyst
A + B <--> AB
a decrease in total pressure
