Chem eqbm relation
Simplify na hora. Feel like 7 mins on this question is too much for an attempt

Also, in this question. The answer is given in Kp but they asked for Keq in question. Whys that?
At 600k , 2mol of NO are mixed with 1 mol of O2.
2NO(g)+O2(g)⇄2NO2(g)
The reaction occurring as above comes to equilibrium under a total pressure of 1 atm. Analysis of the system shows that 0.6 mol of oxygen are present at equilibrium. The equilibrium constant for the reaction is__.

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.cos you have gases and usually for gaseous systems, makes sense to use Kp
Also, qeustion says Kp, not Keq
wait you talking about 2 diff questions?
please post separately lol
yea sorry sir
2 diff questions
is this C/2 or C2 (g) ? I assume the latter, could you share your working?
This one says “equilibrium constant” but is given in gases so i should use Kp?
Thats C/2 sir. I couldnt even get to an answer for this question
Nvm c/2 works
really bad handwriting. Also i studied chem eqbm from the vora classes one shot and the teacher said to take total moles, then take mole fraction and multiply Pressure P with it to make partial pressure for each element
i think thats according to dalton law so partial pressure is equal to the molefraction x pressure
well i was so into getting the whole relation, i didnt even focus on the options. :sweaty:
Thats mb
omg dont do so much work . let initial pressure be Po at t=0
at t=t equilibrium pressure of A will be Po-Poalpha , pressure of B will be Poalpha and pressure of C will be Poalpha/2
pressure of A+B+C= P (given)
now write Kp in terms of Po and replace Po with relation in P and alpha obtained from eqn above
shouldnt take more than a minute or so
