Answer #1

1)

th "quotient" Q is given as

Q = [CO][H2]/[H2O]

carbon concentration is ignored since it is a solid; activity = 1

therefore; calculate concnetrations

M = mol/L

n = 14.1 mol of H2O

M = 14.1/2.25 = 6.26666 M of H2O

n = 3.60 mol of CO

M = 3.60 /2.25 = 1.6 M of CO

8.50 mol of H2

M = 8.5/2.25 = 3.777 M of H2

Then

Q = [CO][H2]/[H2O] = (1.6)(3.77)/(6.266) = 0.962655

Q = 0.962655
