A reaction between the substances A and B has been found to give the following data :
3A + 2B = 2C + D
Homework Answers
Step2 if we compare 2nd and 3rd observations ; conc of A is doubled while conc of B remains same ; the reaction rate becomes 4 times. Thus order ofreaction with respect to A is 2
Step3 total order = 2+3 =5
