Key Formulas and Equations

Calculate the temperature of air compressed adiabatically in a one-cylinder diesel engine from 1060 cc at 25°C to 60 cc. Given that Cy = (5/2)R, compute Q, W, AH, and AU for this compression. 

Use heats of combustion to calculate the A//298.15 for 3HC = CH C6Hg. Although this reaction seems like an improbable stereospecific termolecular collision is required in the gas phase, it does occur on surfaces so much so that high-pressure tanks of acetylene have added impurities to inhibit the formation of benzene. 

Given that 0.500 g of n-heptane (C7H16) burned in a constant volume combustion calorimeter with Cy= 1954 cal/°C causes AT = 2.934°C at Tave = 25°C, calculate the molar for
