Question
Part A
Which of the following statements is true?
If H0R for a chemical reaction does not change appreciably with temperature, the heat capacities for reactants and products must be small.
A) If H0R for a chemical reaction does not change appreciably with temperature, the reactants and products must be in their standard reference states.
B) If H0R for a chemical reaction does not change appreciably with temperature, the difference between the heat capacities for reactants and products must be small.
C) If H0R for a chemical reaction does not change appreciably with temperature, the temperature must be close to 298.15 K.
D) Which of the following statements is true?

Please explain! Thank you!
C and D A and D B and D C onlyExplanation / Answer
C) is true, since H0R is referenced to STP, that is, temperature 25ºC or 298.15 K; P = 1 atm and elemental species.
When you heat a species (change its temperature) you will have differencees between dH
All other are false
