## Homework Statement

The Equilibrium constant for A(g) -> 2B(g)

is 1x10^-2 at 1000k. Calculate the fraction on A which is dissociated at 1000k if the total pressure is

1 atm

10^-3 atm

## Homework Equations

PV=nRT

B^2 / A = Ke (1x10^-2)

## The Attempt at a Solution

for A PV=1x8.714x1000 = 8.714x10^3

for B PV=2x8.714x1000 = 17.428

All i can work out from this is that theres gunna be a 1:2 ratio? Im completely lost and my minds gone blank. Thanks in advance for the help
