Question

What is the equilibrium concentration

of C at 30°C for the gaseous reaction
A + B <-> 2C
if Kc = 4.0 and [Al]i = [B]i = 2.0 M ?
[?]M

Answer 1

`\\ \rm\Rrightarrow K_c=([Products])/([Reactants])`

Now

`\\ \rm\Rrightarrow k_c=([C]^2)/([A]^1[B]^1)`

Put values

• [C] be x

`\\ \rm\Rrightarrow 4=(x^2)/(2^2)`

`\\ \rm\Rrightarrow x^2=4(4)`

`\\ \rm\Rrightarrow x^2=4^2`

`\\ \rm\Rrightarrow x=4.0M`
