Question

Use this equation to find the equilibrium constant?

Answer 1

Well, the hard part was to come up with the equation for the reaction

`2"N"_2"O"(g) + "O"_2(g) rightleftharpoons 4"NO"(g)`...

now use it. It is just plugging numbers in and using a calculator:

`K_c = (5.6 xx 10^(-9) "M")^4/(("0.0035 M")^2("0.0027 M")) = ???`

From where did the exponents originate? On a further note, it is a must to understand what the equation means...

In that regard, what would happen if the concentration of `"N"_2"O"` was doubled? Could `K_c` change, or would the equilibrium be disturbed, and then be inclined to shift back to equilibrium and establish the same `K_c` again? Which direction would the equilibrium shift if this were to occur (right or left)?
