Question

For the given reaction,
$A+B_{2} \rightarrow AB+B$
the rate of the reaction is directly proportional to the concentration of $A$ and independent of concentration of $B_{2}$ . Determine the rate law.

• A. $k\left[\right.A\left]\right.\left[\right.B_{2}\left]\right.$
• B. $k\left[\right.A\left]\right.^{2}\left[\right.B_{2}\left]\right.$
• C. $k\left[A\right]$
• D. $k\left[\right.B_{2}\left]\right.$

Answer 1

Answer: (C)

The rate of the reaction $A+B_{2} \rightarrow AB+B$ ; is directly proportional to the concentration of A and independent of concentration of $B_{2}$ , hence, rate law is:
Rate $=k\left[A\right]\left[B_{2}\right]^{0}$
