1)For a given reaction, the rate constant doubles when the temperature is increased from 43.5 °C to 71.5 °C. What is the activation energy for this reaction? (R = 8.314 J/KÃmol)
___kJ/mol
2)The vapor pressure of liquid carbon tetrachloride, CCl4, is 100. mm Hg at 296 K. A 0.173 g sample of liquid CCl4 is placed in a closed, evacuated 370. mL container at a temperature of 296 K. The molecular mass of carbon tetrachloride equals 153.82 g/mol. (R = 0.08206 L*atm/mol*K, and 1 atm = 760 mmHg)
What will the pressure in the container be when equilibrium is reached?____mm Hg
