In the following hypothetical reaction A+3B hArr 2C+D initial moles of A are twice that of B. If at equilibrium moles of B and C are equal. Percentage of B reacted is

Answer»

0.6
0.4
0.1
0.2

Solution :`{:(A,+,3B,hArr,2C,+,D),(2A,,a,,0,,0),(2a-X,,a-3x,,2X,,x):}`
a-3x=2x(condition given)
`therefore x=(a)/(5)`
The % of b reacted is
`(3x)/(a)xx100=(3)/(a).(a)/(5)xx100=60%`
