Question

Which of the following statements is true about calorimetric studies of chemical reactions?

A) H0Ris determined in a bomb calorimeter and U0R is determined in a constant pressure calorimeter.

B) U0R is determined in a bomb calorimeter and H0R is determined in a constant pressure calorimeter.

C) If either of H0R or U0R is measured, the other quantity can be calculated from the stoichiometric reaction equation.

D) The enthalpy of solution of NaCl in water can only be determined using a constant pressure calorimeter.

Answer Choices:

Explanation / Answer

Solution :-

Internal energy of the reaction is measured in bomb calorimeter and enthalpy change of the reaction is calculated in the constant pressure calorimdeter.

So the correct answer statements are as follows

B) U0R is determined in a bomb calorimeter and H0R is determined in a constant pressure calorimeter.

C) If either of H0R or U0R is measured, the other quantity can be calculated from the stoichiometric reaction equation

So B and C are correct answers
