Assertion (A) : 4 moles of

{KClO}_3

(50 % pure) gave 3 moles of

\mathrm{O}_2

on heating strongly and thus yield is

100 \%

2{KClO}_3 \longrightarrow 2 {KCl}+3 {O}_2

Reason (R) : 3 moles of

{O}_2

are obtained from 2 moles of

{KClO}_3

View answer and explanation

Correct option: B

Both

\mathbf{A}

and

\mathbf{R}

are true but

\mathbf{R}

is not the correct explanation of

\mathbf{A}

Option B (Both

\mathbf{A}

and

\mathbf{R}

are true but

\mathbf{R}

is not the correct explanation of

\mathbf{A}

) is correct because both the assertion and the reason are true statements, but the reason does not explain why the yield is 100%.
