g Suppose a 49. L reaction vessel is filled with 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium

The question is incomplete, the complete question is:

At a certain temperature, the equilibrium constant for the following reaction is 0.74:

Suppose a 49.0 L reaction vessel is filled with 1.5 mol of and 1.5 mol of NO. What can you say about the composition of the mixture in the vessel at equilibrium?  

A. There will be very little and NO.

B. There will be very little

C. Neither of the above is true.

The correct option is B. there will be very little

Explanation:

We are given:

Initial moles of = 1.5 moles

Initial moles of NO = 1.5 moles

Volume of vessel = 49 L

As, moles of reactants and moles of products are equal, the volume term will not appear in the equilibrium constant expression.

Equilibrium constant for the reaction = 0.74

For the given chemical equation:

Initial:                            1.5           1.5             -

At eqllm:                     1.5-x        1.5-x            2x

The expression of equilibrium constant for the above reaction:

Putting values in above equation, we get:

Neglecting the negative value of equilibrium constant because concentration cannot be negative

Equilibrium concentration of = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of NO = (1.5 - x) = (1.5 - 0.451) = 1.049 moles

Equilibrium concentration of = 2x =

There are 3 possibilities:

Here, the value of , which is less than 1, therefore the reaction is reactant favored and we can say that there will be very little .

Hence, the correct option is B. there will be very little

ok whats the question if not i cannot you i need question and need a thing to answer
