The following data pertains to reaction between A and B :
S.NO.[A]mol L−1mol L−1Rate(mol L−1time−1)11.0×10−22.0×10−22.0×10422.0×10−22.0×10−24.0×10−432.0×10−24.0×10−28.0×10−4
Which of the following inference(s) can be drawn from the above data ?
1. Rate constant of the reaction is 1.0×10−4
2. Rate law of the reaction is: rate =k[A][B]
3. Rate of reaction increases four times on doubting the concentration of both the reactants.
Select the correct answer using the codes given below:
2 and 3
Rate law : d[A]dt=k[A]x[B]y
Doubling [A], rate is doubled. Hence 2x=2,x=1
Similarly y=1;d[A]dt=k[A][B]
k=rate[A][B]=2.0×10−41×10−2×2×10−2=1(rate)2(rate)1=k(2[A])(2[b])k[A][B]
