Question

Chemical Equilibrium: Please explain the method to solve the question attached.

Ans is 2.25 but I need the solution.

Thanks a lot!!​

Answer 1

Explanation:

i have applied the method.. i am getting a round up answer because i neglected many decimal places...

if you observe the equations... reverse and half of eq1 plus half of eq2 gives us the desired equation..

but in equilibrium when we have have such a situatio where we have to add the k of 2 equations to get a desired eq we multiply the two ks..

but since we have to half the k of the two equations we have to find the square root of k1 and k2... then do 1/k1... becuase we need the reverse of the equation .. thrn multiply...ie

k=(1/√k1)×√k2...

√k1=4.5×10^-7

√k2=1.1×10^-6

k=(1/4.5×10^-7)×1.1×10^-6

k=2.44

its not the exact answer... but i hope its right..
