@ shahi 
below are the steps to solve the question 
N2O4 – 2NO2 ( this is a reversible reaction ) 
t=0    1      0 
t= equi 1- alpha      2 alpha 
kp = ( 2 alpha ) ^2 / 1- alpha 
2 = 4 alpha square / 1- alpha 
4 alpha square + 2 alpha -2 =0 
so, we are getting 2 value here 
alpha = ½ , and alpha = -1 
so, as alpha cannot nagative here , so, answer will be ½ 
HOPE IT CLEARS 
ALL THE BEST ./.
