H2+12 <-->2 HI : Consider the synthesis of hydrogen iodide as a reaction that has reached equilibrium. If the pressure of this system were decreased, what is most likely to occur?
The amount of hydrogen gas will increase.
The amount of iodine gas will increase.
The amount of hydrogen iodide will increase.
There will be no change.

the answer would be a

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
