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.
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.
To determine the effect on the temperature of water in the calorimeter, we need to consider whether the reaction is exothermic or endothermic.
In an exothermic reaction, heat is released, causing an increase in temperature. In an endothermic reaction, heat is absorbed, resulting in a decrease in temperature.
To figure out whether the given reaction is exothermic or endothermic, we need to examine the reaction equation and the nature of the substances involved.
In this reaction, CH3COOH (acetic acid) reacts with Na2CO3 (sodium carbonate) to produce NaCOOCH3 (sodium acetate), H2O (water), and CO2 (carbon dioxide). This reaction involves the breaking and formation of bonds.
Since the reaction is stated to "proceed by absorption of heat," it indicates that the reaction is endothermic. This means that the reaction absorbs heat from the surroundings, including the water in the calorimeter.
Therefore, the effect on the temperature of the water in the calorimeter will be a decrease. Thus, the correct answer is b) Temperature of water decreases.
