Amixture of two gases exerts a total pressure of 2.25 atm. if the partial pressure of one of the gases is 1.43 atm, what is the partial pressure of the other gas in the mixture?

Answer :  The partial pressure of other gas in a mixture is, 0.82 atm

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

where,

= total partial pressure = 2.25 atm

= partial pressure of one gas = 1.43 atm

= partial pressure of another gas = ?

Now put all the given values is expression, we get the partial pressure of the another gas.

Therefore, the partial pressure of other gas in a mixture is, 0.82 atm

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.
