If samples of hydrogen and iodine with partial pressures of 0.400 and 0.100 respectively at 430 degree celcius (where K = 50) were sealed in a flask and the reaction left at this temp to come to equilibrium find
a) the equib partial pressures of the three gases.

ok so i am a bit stuck. I made an I.C.E table and came up with this equation


Which i simplified to this

now i am stuck , i worked out the quadratic and got x = 0.4221 & x = 0.09871.
I put them into the original equation and it doesnt come out right.

Can someone please help me!

Don't know if it is just me, but I can't see your diagrams

i dont know why they arn't coming up. nvm i think i have figured this out anyway , was a calculation error.

Hmm...did you get the partial pressure of H₂ as 0.3025?
