Question

A solution of 500 ml of 0.2 M KOH and 500 ml of 0.2 M HCl is mixed and stirred; the rise in temperature is T 1 . The experiment is repeated using 250 ml of each solution, the temperature raised is T 2 . Which of the following is true - (A) T1=T2 (B) T1=2 T2 (C) T1=4 T2 (D) T2=9 T1

500 mL of 0.2 M KOH (S.B.) (Use q = mC Δ T) 500 of 0.2 M HCl (S.A.) The heat of neutralisation is same T 1= T 2

Q. A solution of $500 m l$ of $0.2 M K O H$ and $500 m l$ of 0.2 {\,}M $H Cl$ is mixed and stirred; the rise in temperature is $T_{1} .$ The experiment is repeated using $250 m l$ of each solution, the temperature raised is $T_{2} .$ Which of the following is true -

$T_{1} = T_{2}$

$T_{1} = 2 T_{2}$

$T_{1} = 4 T_{2}$

$T_{2} = 9 T_{1}$

$500 m L$ of $0.2 M K O H$ (S.B.) (Use $q = m C Δ T$ )

500 of $0.2 M H Cl$ (S.A.)

The heat of neutralisation is same

$T_{1} = T_{2}$
