As for thermal reactions complex photoreactions can be the result of more than one step of the reaction. By analogy one can correlate a partial photochemical quantum yield to each of the partial steps of the reaction (2.14)φkAi=x˙k/IAi,i=1,2,…,n+≤n,k=1,2,…,s+≤s. IAi is ...
Taking into account that selectivity and yield can be expressed in many ways, when reporting their values we strongly advice to specify the definition used and, eventually, the units. Example 8.2 Complex reactions The following reactions may be considered at the catalytic burning of ammonia: (i)...

For many chemical reactions, the rate is proportional to the concentration of a reactant [A] as expressed by the following: [1]Velocity=K1A1=K1A [2]Velocity=K0A0=K0 where k1 is the first-order rate constant and [A] is the concentration of A. If the velocity is independent of the ...
