Question

Chemical Thermodynamics

Propane (C,H,) is burned in a combustion chamber at a flow rate of 15.00 m/min with 25.0% excess air. If the propane and air streams enter the chamber at 22.0 °C and 1.30 atm (absolute), and the products leave the chamber at 255.0°C and 2.20 atm(absolute), what is the volumetric flow rate of product gas from the chamber? Assume 100% conversion and ideal behavior.To solve for the flow rate, first label the process flow diagram. Label any quantities as "unknown" if they are not given or implied and "none" if the quantity is zero. Do not leave any blank spaces. Variable names are given for reference later.

Use the ideal gas law to find the molar flow rate of propane into the combustion chamber.

What is the molar flow rate of air into the combustion chamber?
