Question

when a mixture of 10 moles of SO2 and 16 moles of O2 WERE PASSED OVER A CATALYST ,8 MOLES OF SO3 WERE FORMED AT EQUILIBRIUM .THE NO. OF MOLES OF OF SO2 AND O2 REMAINING ARE

Answer 1

SO2 moles remained 2
and 12 moles of O2 remained

Answer 2

2SO2(g)+O2(g)--------->2SO3(g)

t=0 10 16 0

teq.(10-2x) (16-x) 2x

2x=8,ie.,x=4

RemainingSO2=10-8=2mol

RemainingO2=16-4=12mol
