The reaction 2H2O2 MnO2 undergoes is a decomposition reaction, where hydrogen peroxide (H2O2) breaks down into water (H2O) and oxygen gas (O2) in the presence of manganese dioxide (MnO2) as a catalyst.
2H2O2 --> 2H2O + O2Catalyzing this reaction. The breakdown of hydrogen peroxide into water and oxygen gas.
The reaction 2H2O2 --> 2H2O + O2 is spontaneous because it results in the formation of more stable products with lower energy compared to the reactant hydrogen peroxide (H2O2). This indicates a decrease in Gibbs free energy (∆G<0) and the reaction can occur without requiring an external energy source.
exothermic
This is an endothermic reaction.
The reaction 2H2O2 MnO2 undergoes is a decomposition reaction, where hydrogen peroxide (H2O2) breaks down into water (H2O) and oxygen gas (O2) in the presence of manganese dioxide (MnO2) as a catalyst.
decomposition
The disproportionation of hydrogen peroxide is represented by the following reaction: 2H2O2 - 2H2O O2
The reaction is: 2 H2O2 -------------2 H2O + O2 The hydrogen peroxide is the reactant; water and oxygen are the products.
The half reaction for the decomposition of hydrogen peroxide (H2O2) is: 2H2O2 - 2H2O O2
The balanced half reaction for the oxidation of hydrogen peroxide is: 2H2O2 - O2 2H 2e-
The reactant is hydrogen peroxide (2H2O2), which decomposes into water (2H2O) and oxygen gas (O2) as the products in this decomposition reaction.
2H2O2(g) 2H2O(g) + O2(g)
2H2O2 --> 2H2O + O2Catalyzing this reaction. The breakdown of hydrogen peroxide into water and oxygen gas.
The reaction 2H2O2 --> 2H2O + O2 is spontaneous because it results in the formation of more stable products with lower energy compared to the reactant hydrogen peroxide (H2O2). This indicates a decrease in Gibbs free energy (∆G<0) and the reaction can occur without requiring an external energy source.
4H2O2 --> 4H2O + 2O2 That would be 2: one mol of O2 for every 2 mols of H2O2.
There isn't one because there is no reaction beyond the catalysis of the decomposition of the peroxide.
