1. How much heat in kilojoules is needed to bring 2.00 kg of water from 27.7 to 82.6 ¡ãC (comparable to making four cups of coffee)?
2. Consider the reaction:
CH4(g) + 2O2(g) ¡ú CO2(g) + 2H2O(g)
Use data in table below
Compound S¡ã, J¡¤mol-1¡¤K-1
CH4(g) 186.2
O2(g) 205.0
CO2(g) 213.6
H2O(g) 188.7
a. calculate ¦¤S¡ã in J¡¤K-1.
-----?-------J¡¤K-1
b. From the standpoint of entropy only this reaction
i) is not spontaneous.
ii) occurs spontaneously.
