question 6 into a K, value. Assume the Ke was determined at 25°C.
6. Write the expression for K. for the production of 4 moles of H₂(g). (Hint: How does chemical equation change?) 82 (Ha] [S₂]² Kc = CHSS2
Ahswer the remaining questions based on the following reaction. Cl₂(g) + PC3(g) PCIs(g) Oat 7. If the equilibrium amounts of Clz, PCI3, and PCIs are 2.1, 5.4 and 3.6 moles respectively in a 10.0 L flask, use the original given chemical equation to calculate K. for the reaction. 8 Kc = Singa 0.36 0.21x0.54 3.17 Ke: Ke=
8. Since all of the components of this reaction are gases, the equilibrium constant can also be written as a Kp value. The equation to convert between K. and Kp is Kp Ke (RT)n, where R is the gas constant (0.0821L atm/mol K), T is the temperature in Kelvin, and an is the change in the number of moles over the course of the reaction (moles gaseous products - moles gaseous reactants). Convert the value of Ke that you calculated in 8. Since all of the components of this reaction are gases, the equilibrium constant can also be written as a Kp value. T
