The rate law for the reaction A + B → product is rate = k [ A ] [ B ] . When will the rate of reaction increase by factor two?

Rate = k [ A ] [ B ] ( Rate ) 1 = k × 2 [ A ] [ B ] Rate ( Rate ) 1 = k [ A ] [ B ] k 2 [ A ] [ B ] = 2 ( Rate ) 1 = 2 × Rate

The rate law for the reaction $A + B \to$ product is rate $= k [A] [B]$ . When will the rate of reaction increase by factor two?

Answer:

Solution:

$Rate = k [A] [B] (Rate)_{1} = k \times 2 [A] [B] \frac{( Rate ) _{1}}{Rate} = \frac{k 2 [ A ] [ B ]}{k [ A ] [ B ]} = 2 (Rate)_{1} = 2 \times Rate$
