At 2000°C, the equilibrium constant for the reaction below is Kc = 4.10 ´ 10–4 . If 0.600 moles of NO is placed in a 1.0-L reaction vessel, what will the equilibrium concentration of N2 be?

At equilibrium, the concentration of is going to be 0.30M

Explanation:

We first need the reaction.

With the information given we can assume that is:

+ ⇄ 2

If there is placed 0.600 moles of NO in a 1.0-L vessel, we have a initial concentration of 0.60 M NO; and no nor   present. Immediately, and are going to be produced until equilibrium is reached.

By the ICE (initial, change, equilibrium) analysis:

I: []=0   ;     [ ]= 0    ; []=0.60M

C: []=+x   ;     [ ]= +x    ; []=-2x

E: []=0+x   ;     [ ]= 0+x   ; []=0.60-2x

Now we can use the constant information:

=

At equilibrium, the concentration of is going to be 0.30M

k

explanation:

k

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
