In a gaseous phase reaction A_(2)(g)toB(t)+1(1//2)C(g), the increase in pressure from 100 mm to 120 mm is noticed in 5 minute.The rate of disappearance of A_(2) in mm "min"^(-1) is

Answer»


SOLUTION :`A_(2)to B+1/2C`
`100""0""2`
`(100-x)""x""x/2`
`60""40""20`
`implies100-x+x+x/2=120,r_(A_(2))=(d(P_(A_(2))))/(DT)=(100-60)/5=40/5=8`
