Question

For reaction 2A + B $\longrightarrow$D + E, following mechanism has been proposed

mechanism A + B $\longrightarrow$ C + D ...... Slow

A + C $\longrightarrow$ E ..........fast

Rate law for the reaction

• A. r = K[A]²[B]
• B. r = K[A][B]
• C. r = K[A]
• D. r = K[A][C]

Answer 1

Answer: (B)

r = KA$$$$B

Answer 2

R.D.S = step ,

R = K[A]'[B]'
