For the reaction,  \[A\left( g \right)\text{ }+\text{ }2B\left( g \right)\to C\left( g \right)\text{ }+\text{ }D\left( g \right)\] \[\frac{dx}{dt}=K[A]{{[B]}^{2}}\] Initial pressure of A and B are respectively 0.60 atm an 0.80 atm. At a time when pressure of C is 0.20 atm, ratio of initial rate and final rate is y. What is the value of y?
