Consider the following question.

Question

Consider the following reaction:

A+2B⇌2C. K=10

What is K for the reaction 2A +4B ⇌ 4C2A + 4B ⇌ 4C

a)20

b)none of these

c)The same

d)100

Answer 1

The answer is K=100. K for the new reaction is [C]^4/[A]^2{B]^4, which is the square of K for the old reaction [C]^2/[A][B]^2.
