FOP Practice 15.7 - Enhanced with Feedback Review | Constants Part A Consider the reaction and its equilibrium constant: N2O4(g) = 2NO2(g) K. = 5.85 x 10 (at some temperature) Calculate Qc at the given concentrations. -3 Express the reaction quotient to three significant figures. A reaction mixture contains [NO2] = 0.0242 M and [N2O4] 0.0350 M. ΑΣφ You may want to reference (Pages 653 - 656) Section 15.7 while completing this problem. Qc =

For the reaction 2 SO,(g) + 0,(g) =2 SO;(g) the equilibrium constant is K. = 15 M-' at 850 K. Three sets of concentrations are given for the three gases in the reaction. For each set, predict the direction in which the net reaction will proceed toward equilibrium. Left No change Right Answer Bank [so,] = 0.20 M [0.] = 0.60 M [so,] = 0.60 M [so,] = 0.72 M [0] = 0.69 M [So,] = 0.63 M [So,] = 0.12 M [0] = 0.12 M so,] = 0.56 M
