Portable lanterns and stoves used for camping often use a mixture of hydrocarbons for fuel. One such hydrocarbon is an alkane called n-pentane. These lanterns and stoves
are often difficult to light on a cold day because the fuel has a low vapor pressure at low
temperatures. Determine the vapor pressure of n-pentane on a night when the temperature
is 0.0 °C. The enthalpy of vaporization of n-pentane is 27.6 kJ/mol, and its boiling point
is 36.0 °C.
A) 228 torr
B) 367 torr
C) 184 torr
D) 479 torr
E) 209 torr

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.
