Question
Hydrogen peroxide decomposes to water and oxygen as shown in the following reaction2H2O2 <-> 2H2O + O2
The activation energy for the unanalyzed reaction at 20 0C is 18 Kcal/mol, and the standard free energy change for this reaction is -200kcal/mol. The catalase ( EA =7 kcal/mol) and iron containing enzyme
A) Draw the activation energy diagram ( X- axis reaction progress and Y axis energy) for the unanalyzed and catalyzed versions of this reaction under standard conditions. Be sure to label EA and delta G (noting their Quantative values) and list reactants and product for each graph.
Explanation / Answer
get the mass of the two moles of H2O2 in the balanced equation above all atomic wts. in 2H2O2 add to 64, so if two moles or 64 grams of hydrogen peroxide decompose, 0196 kJ of heat energy is releast. But we are only reacting 28.7 g of hydrogen peroxide, so we will only release a fraction of the -196 kJ or 28.7 over 64 grams/mole X -196 kJ = -85.13 Kj
