What is the reaction quotient, q, for this system when [n2] = 2.00 m, [h2] = 2.00 m, and [nh3] = 1.00 m at 472°c?

Answer : The value of reaction quotient, Q is 0.0625.

Solution : Given,

Concentration of = 2.00 M

Concentration of = 2.00 M

Concentration of = 1.00 M

Reaction quotient : It is defined as a concentration of a chemical species involved in the chemical reaction.

The balanced equilibrium reaction is,

The expression of reaction quotient for this reaction is,

Now put all the given values in this expression, we get

Therefore, the value of reaction quotient, Q is 0.0625.

the first answer is 0.0625

the second one is Q < Keq

After one set of hydrogen and oxygen molecules have reacted, the energy released triggers molecules in the surrounding mixture to react, releasing more energy. The result is an explosive, rapid reaction that releases energy quickly in the form of heat, light and sound.
