Q 8
Reaction is non spontaneous (mentioned in para)and if beta is equal to 0.7 and you plug in this value in expression calculated in Q 7 then this will result in K>1 which makes the process spontaneous.

They calculated beta value as 0.7 which  you need to prove that it is wrong.
Plug in expression calculated in Q7

Delta G is positive as mentioned in paragraph
so Kc<1 is correct  ...this means reaction is non spontaneous.
