Abstract:

For reaction α A→p, the rate equation is as follows: differential formula: （1） integral formula： （2） （3）Or： （4） （5）
Obviously ，the plot of vs t (n≠1)or vs t (n = 1)must be a straight line Trying the variable n and using the criterion of correlation coefficient, the best n can be found. Or by substituting the variable n in (3) or (5), and using the criterion of standard deviation, the best n can slao be found,which is just the order of reaction.

Key words: Reaction Equations, Trial and Error method, Microcomputer
