Energy to break bonds is less than energy release to form bonds.
is what type of reaction?

The reaction is a exergonic reaction.

An exergonic response is a synthetic response where the adjustment in the free vitality is negative demonstrating an unconstrained response. For procedures that occur under steady weight and temperature conditions, the Gibbs free vitality is utilized though the Helmholtz vitality is utilized for procedures that happen under consistent volume and temperature conditions.  

In exergonic reaction, during bond breakage energy is required whereas the formation of the bond releases energy. Although exergonic responses are said to happen immediately, this doesn't infer that the response will occur at a perceptible rate.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

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.
