the following reaction was carried out In a 4.00L reaction vessel at 1100 K: If during the course the reaction, the vessel is found to contain 8.00mol of C, 14.0 mol of H2O, 3.60 mol if CO, and 6.70 mol of H2, what is the reaction quotient Q?Q=? the following reaction was carried out In a 4.00L reaction vessel at 1100 K: If during the course the reaction, the vessel is found to contain 8.00mol of C, 14.0 mol of H2O, 3.60 mol if CO, and 6.70 mol of H2, what is the reaction quotient Q?
Q=? the following reaction was carried out In a 4.00L reaction vessel at 1100 K: If during the course the reaction, the vessel is found to contain 8.00mol of C, 14.0 mol of H2O, 3.60 mol if CO, and 6.70 mol of H2, what is the reaction quotient Q?
Q=?
Explanation / Answer
concentrations of all species : M = moles / volume
[C] = 8/4 = 2 M
[H2O ] = 14/4 = 3.5 M
[CO]= 3.60/4 = 0.9 M
[H2]=6.70/4 = 1.675 M
C (s) + H2O (g) ---------------------------> CO (g)+ H2 (g)
2 3.5 0.9 1.675
Q = [CO][H2]/[H2O]
Q = (0.9) (1.675)/3.5
Q = 0.43
the reaction quotient Q = 0.43
