A reaction is second order with respect to and independent of The rate expressio
A reaction \( A+B \rightarrow C \) is second order with respect to \( A \) and independent of \( B \) The rate expression for the reaction is:
- A. \( r a t e=K[A][B] \)
- B. rate \( =K[A]^{2}[B] \)
- C. \( r a t e=K[A]^{2}[B]^{2} \)
- D. rate \( =K[A]^{2} \)
Step-by-step solution
The reaction is second order with respect to A, so the exponent on [A] is 2. It is independent of B, so the exponent on [B] is 0. Thus, the rate law is rate = k[A]^2[B]^0 = k[A]^2.
