How to measure the S/N ratio to evaluete functionality of a chemical reaction process where we can obsearve only fraction ratios of input main material consumed or of objective material produced, quite often both. The former fraction ratio is denoted by q and the later by p. when there are many observations obtained at various times at each reaction process, the way of calculating S/N is from the following ideal relation is introduced in this article. Where T is the time at which p and q were observed. only one pair of p and q is available, the way of measuring S/N is also discussed in section 1.4 and 1.5.
