The reaction quatient Q is 0.306

Explanation:

Step 1: data given

Volume = 2.50 L

Temperature = 1100 K

Number of moles C = 6.75 moles

Number of moles H2O = 13.5 moles

Number of moles CO = 3.10 moles

Number of moles H2 = 9.00 moles

Step 2: The balanced equation

C (s) + H2O (g) ⇌CO (g) + H2 (g)

Step 3: Calculate the concentration

Concentration = moles / volume

[C] = 6.75 moles / 2.5 L

[C] = 2.7 M

[H20] = 13.5 moles / 2.5 L

[H2O] = 5.4 M

[CO] = 3.10 moles / 2.5 L

[CO] = 1.24 M

[H2] = 9.00 moles / 2.5 L

[H2] = 3.6 M

Step 4: Calculate Q

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

Q = (1.24 * 3.6) / (2.7*5.4)

Q = 0.306

The reaction quatient Q is 0.306
