Question

What is the maximum amount of SO3 that could be obtained from 25 g of SO2 and 6 g of O2 by the
following reaction? 2SO2(g) + O2(g)

2SO3(g)​

Answer 1

2SO

2

+O

2

→2SO

3

As per the balanced chemical equation, 2 moles of SO

2

will react with 1 mole of O

2

to form 2 moles of SO

3

.

Hence, 0.25 moles of SO

2

will react with 0.25×

2

1

=0.125 mole of O

2

to form 0.25×

2

2

=0.25 moles of SO

3

.

Hence, the maximum number of moles of SO

3

that can be produced is 0.25 moles
