A sample of air with a mole ratio of to of is heated to 2500 K. When equilibrium is established in a closed container with air initially at 1.00 atm, the mole percent of NO is found to be 1.8%. Calculate for the reaction. N2(g) + O2(g) 2 NO(g) Kp N2 O2 79 : 21 Kp = 1.6 * 102 SO -5 3(g) 2 SO2(g) + O2(g) SO3(g) N2O4 2 NO2(g) Kp = 0.113 at 298 K N2O4(g) 3.00 * 10-3 mol N2O4 0.0240 mol N2O4 initially * 100% = 12.5%
CHAPTER 4 TYPES OF CHEMICAL REACTIONS AND SOLUTION STOICHIOMETRY Aqueous Solutions: Strong and Weak Electrolytes 10. The electrolyte designation refers to how completely the dissolved solute breaks up into ions. Strong electrolytes completely break up into ions when in water, weak electrolytes only partially break up into ions (less than 5% usually), and nonelectrolytes do not break up into
