Question

When a mixture of 10 mol of so2 and 15 mol of o2 was passed ovwr catalyst 10 mol of so3 was formed howmany mol ofso2 &o2 not tre?

Answer 1

2 SO2 + O2 = 2 SO3

Multiply by 5

10 SO2 + 5 O2 = 10 SO3

5 moles of O2 is consumed for the conversion of 10 moles of SO2 to 10 moles of SO3.

There will be a remaining of 10 moles of O2.

SO2 will get consumed comp;etely.
