Which catalyzed reaction breaks up ozone? a: 2h2o2(l) -> mno2 2h2o(l) + o2 b: o3 + o -> cs 2o2 c: 2h2o2 (aq) -> pt3 2h2o(l) + o2 d: o2 + 2so2-> no 2so3

B. O₃ + O → CS + 2O₂

Explanation:

The break up of ozone occurs when a molecule of ozone (O₃) reacts and produces the molecule of oxygen (O₂). It can happen from a lot of ways, but in the statements given, only in letter B it is happening.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
