13. Many smokers will agree that the butane is a common fuel used in cigarette lighters and camping stoves in south Africa. That organic solvent is stored under pressure, and exists as a mixture of liquid and gas. A high temperature may cause the container to explode. At , the vapor pressure of butane is . What is the pressure in the container at 14. Sulfur dioxide is produced in enormous amounts for sulfuric acid production. It melts at and boils at . Its fus is , and its vap is 25.73 . The specific heat capacities of the liquid and gas are and , respectively. How much heat is required to convert of solid at the melting point to a gas at ?
Expert Answer
Question 13.To find the pressure of butane at 119 °C, you can use the Clausius-Clapeyron equation, which relates the vapor pressure of a substance to its temperature and enthalpy of vaporization. The equation is: where are the vapor pressures at temperatures , is the enthalpy of vaporization, and R is the gas constant. You are given that = 2.30 atm and = 25 °C (or 298 K) at standard conditions. You also know that = 24.3 kJ/mol and R = 8.314$ J/mol K. You need to find .
