A 7.24 g sample of cycloheptane (formula C7H14), is mixed with 14.88 atm of O2 in a 3.75 L combustion chamber at 157.11 °C. The combustion reaction to CO2 and H2O is initiated and the vessel is cooled back to 157.11 °C. Report all answers to two decimal places in standard notation (i.e. 1.23 atm).


1. What is PCO2 (in atm) in the combustion chamber assuming the reaction goes to completion? Assume all water is water vapour and that the volume of the system does not change.

Tries 0/13



2. What is PO2 (in atm) in the combustion chamber after the reaction goes to completion?

    1. (18 points) Consider the balanced gas phase combustion of dinitrotoluene, DNT (C7 HG(NO2)2): 2C7H6(NO2)2(g) + 3 O2(g) ---> 14 CO(g) +4 NH3(g). The products are carbon monoxide (CO) and ammonia (NH3). A gaseous mixture of DNT and O2(g) at 80°C is placed into a previously empty rigid container. When the above reaction goes to completion at 80°C, 0.15 atm of O2(g) is still present. The partial pressure of the NH3(g) produced is 1.00 atm. Assume all gases behave ideally....
