A sample of krypton gas occupies 18.60 l at a pressure of 5.540 atm and 35.00 c. what volume would the krypton occupy at stop

91.33 L

Explanation:

For an ideal gas, the product between the gas pressure and the gas volume is proportional to the absolute temperature of the gas. Mathematically:

where:

p is the pressure of the gas

V is the volume of the gas

T is the absolute temperature of the gas

For a transformation of the gas, we can write:

For the sample of krypton in this problem, we have:

(initial pressure)

(initial volume)

(initial temperature)

(final pressure, at stp)

(temperature at stp)

Therefore, the volume at stp is:

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.
