Time left 1:08:34 Consider the following equilibrium reaction: N204 (g) - 2 NO2 (g) N,O, Concentration (mol /L) NO, Time At time t1, heat is applied to the system. Which of the following best describes the equilibrium reaction and the change in Kc? O endothermic and K, increases O endothermic and Ke decreases O exothermic and Ke increases O exothermic and Kç decreases The following reactions have equilibrium values all measured at 500 K. Arrange them in order of increasing tendency to proceed to completion (least completion to greatest completion). 2 NocI - 2 NO + Cl2 Kp = 1.7 x 10-2 I. II. N204 - 2 NO2 Kp = 1.5 x 103 III. 2 S03 - 2 sO2 + 02 Kp = 1.3 x 10-5 IV. 2 NO2 - 2 NO + 02 Kp = 5.9 x 10-5 O IV < III < |< || Il <l< |II < IV III < IV < I < || O II <l< IV < I|
