Enthalpy of Combustion -- Alkanes Write a balanced equation for the cembustion of CH3C3H17(l) (methyl octane) - Le. its resction with O2(g) forming the products CO2(g) and H2O(g. Given the following standard hests of formation: - BH2 of CO2(g) is 393.5k/mol - H of H2O(l is 286kJ/mol - Hf2 of CH3C8H17O(O is 215.5kJ/mol What is the standard heat of reaction (H) for the combustion reaction of CH3C8H1(l) ? 6186,0kJ Ipts Prevlout Tries Calculate the ditference, HE=(PV) for the combustion reaction of 1 mole of methyl octane. (Assume standard wath conditions and 298K for all reactants and products.) The ideal gas law must be used. The incremental change in volume due to liguids is neglected (cf the volume of 1 mole of H2O(l is 18mL, whereas the volume of 1 mol of a gas at 298K is about 24,450 mL. Be careful to accounk for the total change in number of moles of gas molecules (be sure the signs and units are correct too). Note that certain alikanes are gases in the standard state. Learning Goal: To learn how graphs can be used to answer kinetics. questions. A student collected time (t) and concentration ( A) ) data at 295K for the reaction 2AB. These time and concentration data are shown in the table to the right. The studont then plotied graphs of [A] versus t.

A student collected time {t} and concentration ([A]) What is the valuo of the rate constant for this reaction? data at 295K for the reaction 2AB. These time and concentrabien data are shown in the table to the right. Express your answer to three significant figures and include the appropriate units.
