What is the overall reaction represented by this process? Step 1: 2NO(g)N2O2(g) slow Step 2: N2O2(g)+H2(g)H2O(g)+N2O(g) fast Step 3: N2O(g)+H2(g)H2O(g)+N2(g) fast 2NO(g)+2H2(g)2H2O(g)+N2(g) 2NO(g)+N2O2(g)+2H2(g)N2O2(g)+2H2O(g)+N2(g) 2NO(g)+N2O2(g)+2H2(g)+N2O(g)N2O2(g)+2H2O(g)+N2O(g)+N2(g) NO(g)+H2(g)H2O(g)+N2(g) 2NO(g)+2H2(g)+N2O(g)2H2O(g)+N2O(g)+N2(g) NO(g)+2H2(g)+2H2O(g)+N2(g)
