Solution

The correct option is B 50 : 50
For maximum rise in temperature, complete neutralization of acid and bases takes place

so, $N_{1} V_{1} = N_{2} V_{2}$

or, $n_{1} M_{1} V_{1} = n_{2} M_{2} V_{2}$

let volume of KOH $= x m l$ ,

Therefore, volume of $H_{2} S O_{4} = 100 - x$ ml
we get,

$1 \times 1 \times x = 2 \times 0.5 \times (100 - x)$

$x = 100 - x$

$x = 50$

volume of KOH $= 50 m l$

volume of $H_{2} S O_{4} = 50 m l$

Ratio of volumes $= 50 : 50$

Option D is correct.
