Question

Increases as the temperature decreases. The vapor pressure of a solvent over a solution decreases as its mole fraction increases. Nitrogen trifluoride decomposes to form nitrogen and fluorine gases according to the following equation: 2NF_3(g) rightlefttharpoons N_2(g) + 3F_2(g) When 1.10 mol of NF_3 is placed in a 4.00-L container and allowed to come to equilibrium at 800 K, the mixture is found to contain 0.0232 mol of N_2. What is the value of K_p at this temperature? 4.43 times 10^-7 1.75 times 10^-3 7.08 times 10^6 6.78 times 10^-6 1.91 times 10^-3 In an experiment. 0.30 mol H_2 and 0.30 mol l_2 are mixed in a 1,00-L container and the reaction forms HI. If K_C. = 49. for this reaction, what is the equilibrium concentration of HI. I_2(g) + H_2(g) rightlefttharpoons 2HI(g) 0.075 M 0.040 M 0.53 M 0.58 M 0.47 M
