The vapor pressure of benzene is found to obey the empirical equation : ln(p/torr) = 16.725 - 3220.86k/t -118345k^2/t^2 from 298.2k to its normal boiling point 352.24k. given that the molar enthalpy of vaporization at 353.24k is 30.8kj/mol and that the molar volume of liquid benzene at 353.24k is 96.0 cm^3/mol, use the above equation to determine the molar volume of the vapor at its equilibrium pressure at 353.24k and compare this value with the ideal-gas value.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
