Explanation / Answer

Rate of reaction depends upon slow step . is is called rate determining step.

C + D --------> CD (fast)

CD + D ------> CD2 (slow)

CD + D -------> CD3 (fast)

-----------------------------------------------

C + 3D-------------->CD3 over all reaction

Rate law

Rate = K*[CD]^1*[D]^1

Step1 :   A + B -------> C (fast)

Step2 : B + C ------> D ( Slow)

SLow step is rate determing step.

Rate la

Rate = K*[B]^1*[C]^1
