Should you invest in an engine that is said to burn air at room temperature when you were told that a special chamber allows oxygen to combine with N2 to form NO2 (nitrogen dioxide)using the reaction below.
1/2N2(g) + O2(g)—>NO2(g)
Calculate ^H, ^ S then ^G
N:B Obtain relevant thermodynamic parameter values from table
Possible signs:
^G= ^H. T^G. Occur
