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?

the first answer is 0.0625

the second one is Q < Keq

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.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
