Chapter 1, Problem 2P
A simple way of looking at the energy associated with the combustion of methane [as shown in equation (1.15)] is to view the oxidation of the carbon by equation (1.13) and the oxidation of hydrogen by equation (1.19). Based on the energies involved in these processes, discuss the validity of this approach.

Question 4
2.5 pts
Nitrogen gas can be combined with oxygen to form nitric oxide (NO) as shown in the following
chemical reaction: N2 (g) + O2 (g) 2 NO (g)
When the reaction is in equilibrium, the concentration of N2, O2 and NO are 280 g/L, 640 g/L, and
750 g/L, respectively. If the concentration of oxygen gas dropped to half, calculate the concentration
of nitric oxide (NO) in g/L when the system returns to equilibrium. (N=14, O=16 g/mol)
