The concentration of the diluted solution is 0.0625 M.
<h3>What is concentration?</h3>
The term concentration refers to the amount of substance present in solution.
1) To find the mass of the compound;
mass/134 g/mol = 1.40x10-2M × 100/1000
mass = 1.40x10-2M × 100/1000 × 134 g/mol
mass = 0.19 g
2) To find the molarity of the solution;
2.50 g/40 = 100/1000 × M
M = 2.50 g/40 × 1000/100
M = 0.625 M
3) Using;
C1V1 = C2V2
0.625 M × 10.00mL = C2 × 100.00 mL
C2 = 0.625 M × 10.00mL/ 100.00 mL
C2 = 0.0625 M

The correct answer should be answer choice B
Answer:
The reaction is not at equilibrium and reaction must run in forward direction.
Explanation:
At the given interval, concentration of NO =
Concentration of =
Concentration of NOBr =
Reaction quotient, , for this reaction =
species inside third bracket represents concentrations at the given interval.
So,
So, the reaction is not at equilibrium.
As therefore reaction must run in forward direction to increase and make it equal to .
