1.2 moles of `SO_(3)` are allowed to dissociate in a 2 litre vessel the reaction is `2SO_(3(g)) hArr 2SO_(2(g)) +O_(2(g))` and the concent ration of oxygen at equilibrium is 0.1 mole per litre. The total number of moles at equilibrium will be

A

2

B

1.4

C

0.8

D

1.6

Text Solution

Verified by Experts

The correct Answer is:
B

Given `(O_(2))=(x)/(2)=0.1 implies x=0.2`
Total no. of moles at equilibrium` = 1.2-2x+2x+x=1.2+x=1.4`
