Question

What is the equilibrium constant based on these concentrations?
Br2: 1.82*10^-2
CH4: 4.33*10^-3
HBr: 3.27*10^2
CBr4: 2.02*10^1

Answer 1

Alright, so Kc = products/reactants

Answer 2

That means, since you don't have any liters, it makes it easier. Just plug in the values.

But first, you need your balanced equation.

Answer 3

[CBr4][HBr]^4/[Br2]^4[CH4]

Answer 4

Good job!!

Answer 5

Now, just plug in your values, making note of the exponents. That will be your eq constant.
