For a hypothetical chemical reaction,
`3A(g)rarr2B(g) + 5C(g)`
if one mole of reactant having V.D = 150 present in a closed container at t = 0. If V.D of gaseous mixture (containing all three gases) after 45 minutes is 50, then total moles of product formed.

A

0.75

B

1.75

C

2.75

D

3.5

Text Solution

Verified by Experts

The correct Answer is:
D
`3A(g) rarr2B(g)+5C(g)`
`t = 0 " 1 "0 " 0"`
`t = 45 " " 1-x " "(2x)/(3) " "(5x)/(3)`
`M_("avg")=("Total mass")/("Total moles")`
`100=(300)/((1-x)+(2x)/(3)+(5x)/(3))" "impliesx = 1.5`
moles of product `=(7x)/(3)=3.5`
