- Consider the reaction: 2 NO(g) + Br2(g) =2 NOBI(g) A chemist placed 0.0322 mol of NO and 1.70 g of bromine (Br2) into a sealed 1.00 L reaction vessel and then allowed the reaction to reach equilibrium. The pressure of the NOBR at equilibrium at 25.0°C is 0.444 bar. (R = 0.08314 L·bar/mol·K and MW of Br2 is 159.808 g/mol.) Calculate the Kp.arrow_forwardAt 1.00 atm and 0 °C, a 5.04 L mixture of methane (CH4) and propane (C₂H₂) was burned, producing 16.5 g CO₂. What was the mole fraction of each gas in the mixture?

Based L-atm on experimentally collected data, the student calculates R to equal 0.0832 mol·K L-atm Ideal gas law constant from literature: 0.08206 mol·K (a) Determine the percent error for the student's R-value. Percent error = % (b) For the statements below, identify the possible source(s) of error for this student's trial. The student notices a large air bubble in the eudiometer after collecting the hydrogen gas, but does not dislodge it. The student does not clean the zinc metal with sand paper. The student does not equilibrate the water levels within the eudiometer and the beaker at the end of the reaction. The water level in the eudiometer is 1-inch above the water level in the beaker. The student uses the barometric pressure for the lab to calculate R.arrow_forwardThe temperature of your water was 22.4 degrees Celsius. The volume of hydrogen collected was 35.3 mL. The atmospheric pressure in the lab room was 29.60 inches Hg. The difference in the water level between the beaker and the burette is 20.0 cm. What was the mass of the magnesium ribbon used?
