Question

For a reaction A+B ⟶P, the following data are provided Entry [A ] in M [B ] in M Initial rate (M/s ) 1 0.02 0.02 2 10^-2 2 0.02 0.04 4 10^-2 3 0.04 0.04 8 10^-2 The rate constant for this reaction in standard unit is

Accepted Answer

Correct answer: D. (d) A+B P According to rate law expression Rate =k [A ]^ [B ]^ (K is constant ) Taking ratio of (1) and (2) entry. ⇒ 4 10^-22 10^-2= [0.04 ]^ [0.02 ]^ [0.02 ]^ [0.02 ]^ 2= [2 ]^ ⇒ [2 ]^1= [2 ]^ Order w.r.t [B ]= =1 Taking ratio of (2) and (3) entry, 8 10^-24 10^-2= [0.04 ]^ [0.04 ]^ [0.02 ]^ [0.04 ]^ Order w.r.t [A] [2 ]= [2 ]^ ⇒ =1 =2 10^-2=k [A ]^1 [B ]^1k= 2 10^-20.02 0.02 = 2 10^-2 10^44= 1002=50

$For a reaction A + B ⟶ P, the following data are provided Entry [A] in M [B] in M Initial rate (M / s) 1 0.02 0.02 2 \times 10^{- 2} 2 0.02 0.04 4 \times 10^{- 2} 3 0.04 0.04 8 \times 10^{- 2} The rate constant for this reaction in standard unit is$
