Answer 1

Answer #1

Firstly we will experiment 2 and 3

While keeping concentration of constant

The concentration of no2 is twiced and the rate of reaction becomes 4 times so we could conclude the rate is proportional to [no2]² hence

reaction order wrt no2 is 2

Now we observe experiment 1 and 2

Concentration of no2 is constant while co is changed but rate remains constant this means that rate of reaction doesn't depends upon co concentration

reaction order wrt co is 0
