Calculating Gas Mixtures: AP Chemistry Quiz on Pressure and Reaction Stoichiometry

In this quiz, Pre-AP and AP Chemistry students are tasked with a problem involving a rigid 5.00 L cylinder containing a mixture of nitrogen (N2) and oxygen (O2) gases. Students must calculate the total pressure of the gas at 298 K, determine the mole fraction of N2 after cooling to 280 K, and analyze how a leak would affect the moles ratio of N2 to O2. Additionally, students will balance the reaction between NO(g) and O2(g) to produce NO2(g) and compare the moles of gas on each side of the reaction equation.

  2. A rigid 5.00 cylinder contains 24.5 g of N2(g) and 28.0 g of O2(g). (a) Calculate the total pressure, in atm, of the gas mixture in the cylinder at 298 K.(b) The temperature of the gas mixture in the cylinder is decreased to 280 K. Calculate each of the following.(i) The mole fraction of N2(g) in the cylinder (ii) The partial pressure, in atm, of N2(g) in the cylinder (c) If the cylinder develops a pinhole-sized leak and some of the gaseous mixture escapes, would the ratio moles of N2(g) / moles of O2(g) in the cylinder increase, decrease or remain the same? Justify your answer.A different rigid 5.00 L cylinder contains 0.176 mol of NO(g) at 298 K. A 0.176 mol sample of O2(g) is added to the cylinder, where a reaction occurs to produce NO2(g).(d) Write the balanced equation for the reaction.(e) Which side of the equation contains more moles of gas: The products or the reactants? Include the number of moles of gas on each side in your answer.
