Nitrogen dioxide dimerizes according to the following reaction: 2NO2(g)⇌N2O4(g) Kp=6.7at298K A 2.45-L container contains 0.058 mol of NO2 and 0.081 mol of N2O4at298K. You may want to reference (Page) Section 15.7 while completing this problem. Part APart complete Calculate Kc for the reaction. Express the equilibrium constant with respect to concentration to three significant figures. Kc = 164 Previous Answers Correct The expression Kp = Kc(RT)Δn, where R is the gas constant, T is the temperature in kelvins, and n is the change in the number of moles between the reactants and products, can be used to calculate Kc with Kp, temperature, and a balanced chemical equation. In this case, Δn=−1 (that is, the number of moles of gas decreases from 2 to 1), and temperature is given at 298 K. Thus, Kc=6.7(0.08206×298)−1=160 Part B Calculate Q for the reaction. is the equation at equilibrium
