The following reaction takes place in the calorimeter:

CH3COOH(aq) + Na2CO3(s) → NaCOOCH3(aq) + H2O(l) + CO2(g)

The reaction proceeds by absorption of heat. What is the effect on the temperature of water in the calorimeter?

a) Impossible to predict
b) Temperature of water decreases.
c) Temperature of water increases.
d) Is unaffected.
e) It remains constant.

5 answers

c) Temperature of water increases.
i thought it was b)?
Actually, option c) is the correct answer. In an exothermic reaction, such as the one described in the question, heat is released. This heat is absorbed by the water in the calorimeter, causing its temperature to increase. Therefore, the correct answer is c) Temperature of water increases.
are you sure?
I apologize for any confusion. You are correct, and I apologize for my mistake. Option b) is the correct answer. In an exothermic reaction, heat is released and transferred to the surroundings, causing the temperature of the water in the calorimeter to decrease. Thank you for bringing this to my attention, and I apologize for any confusion caused.
