What is the ratio K/K, for the following reaction at 723 °C? O2(g) + 3 UO2Cl2(g) = U_08(s) + 3 Cl2(g) A) 0.0122 B ) 1.00 C) 59.4 D) 81.7 6. Use LeCharlier's principle to predict the direction the reaction will proceed using any of the following disturbances to a system at equilibrium: a. Adding a reactant or product b. Removing a reactant or product

Answer 1

O₂ (g) + 3 UO₂Cl₂ (g) $\rightleftharpoons$ U₃O₈ (s) + 3 Cl₂ (g)

As, Kp = Kc (RT)^∆ng

Kc/Kp = 1/(RT)^∆ng ----- (1)

∆ng = (Stiochiometry of product - reactant) that are present in gas phase

= 3-(3+1)

= -1

Temperature = 723°C = 996 K

As Kc is in units of molarity ( mol/L) and Kp is in atm, so R = 0.0821 L atm /K/mol

Putting values in equation (1)

Kc/Kp = 1/ (0.0821 x 996)^-1

= (0.0821 x 996)

= 81.77
