Correct Answer - A
Number of moles of `NaOH=(MV)/(1000)=(0.5xx20)/(1000)=0.01`
Number of moles of `HCl=(MV)/(1000)=(0.1xx100)/(1000)=0.01`
Heat of neutralization `=(-x)/(0.01)=-100x`

`SO_(3) (g)` is produced as : `SO_(2) (g) + (1)/(2) O_(2) (g) hArr SO_(3) (g)` At `900 K, 0.2 `mol of `SO_(2)` and 0.4 mol of `O_(2)` are taken in 2L

Correct Answer - C `{:(,SO_(2) (g),+,(1)/(2)O_(2) (g),hArr,SO_(3) (g),T = 900 K,),("Concentration",(0.2)/(2),,(0.4)/(2),,,,),("initially",,,,,,,),("concentration",0.1 - x,,0.2 - (1)/(2) x,,x,,),(,x = 0.08 M,,,,,,),(,,,,,,,):}` `K_(C) = ([SO_(3)])/([SO_(2)] [O_(2)]^(1//2)) = (0.08)/(sqrt(0.16) xx 0.02) = 10`

The enthalpy of neutralization of oxalic acid by strong acid is `- 25.4 kcal mol^(-1)`. The enthalpy of neutralization of strong acid and strong base

Correct Answer - B Oxalic acid is dibasic acid hence expected heat of neutralization will be `(2xx-13.7kcal)`. The dissociation energy of oxalic acid `2xx13.7-25.4` `=2" kcal "mol^(-1)`
