Answer to Question #25981 in Physical Chemistry for mark
2A(g)+B(g)⇌2C(g)At equilibrium a 6 L container contains 6.0 mol of A, 0.18 mol of B and 3.6 mol of C gases. At a constant temperature the volume of the container is decreased to 4 L and some C gas is added. When the new equilibrium is established, the mole number of B is found to be 0.3. What is the mole number of C gas added into the container???
Equilibrium constant is: K = [C]^2/[A]^2*[B] = (3.6/6)^2 / (6.0/6)^2 * (0.18/6) = 0.36/0.03 = 12
w = 4/6 = 0.667
New K is 12*0.667 = 8 6.0/6-x 0.3 3.6/6+x 2A(g) + B(g) ⇌ 2C(g)
x = 0.37 M real number of moles is 0.37*4 = 1.48 mol
I have no more assignments.
Thank you for all the help! With 19 credit hours, their is always one class that hits the back burner, with your help i was able to get a B in this class and am going to Walk on graduation.
Thank you, Thank you, Thank you!
