In dilute solution the heat of the reaction NaOH + HCl = NaCl + H2O is - 57.3kJ. Therefore the heat of the reaction 2NaOH + H2SO4 ? ? Na2SO4 + 2H2O is

Question 1 Report

In dilute solution the heat of the reaction NaOH + HCl = NaCl + H2O is - 57.3kJ. Therefore the heat of the reaction 2NaOH + H2SO4 $\to$ Na2SO4 + 2H2O is

+ 28.65 kJ

- 28.65KJ

+ 57.3KJ

- 114.6 KJ

- 229.2 KJ

Answer Details

NaOH + HCl = NaCl + H2O $Δ$ H = -57.3kJ

Heat of reaction of 2NaOH + H2O4

NaSO4 + H2O is

= 57.3 x 2 = -114.6 kJ
