Hydrogen peroxide decomposes by the following reaction. The reaction is rapld with the addition of a catalyst. 2 H2O2 (aq) → 2H20 (1) + O2(e) So which choice below holds? entropy and free energy are greater than zero free energy and entropy are less thanzero free energy is greater than zero and entropy is less than tero. free energy is less than zero and entropy's greater than zero
A sample of 900 mol N O is placed in a sealed container, where it decomposer intervenity to Nandoin a first-order reaction.
