<h3>
Answer: 69.1 cm</h3>
Work Shown:
C = 2*pi*r
C = 2*3.14*11
C = 69.08
C = 69.1
This is the approximate distance around the circle, aka the perimeter.
Answer:
Rate of reaction when concentration of A is doubled=0.018 M/s.
Step-by-step explanation:
We are given that for the multi-step reaction
It is given that the rate-limiting step is unimolecular with A as the sole reactant
It means rate of reaction depend upon the concentration of reactant A only
Rate of reaction =k[A]
[A]=0.110 M
[B]=0.110 M
Rate of reaction =0.0090 M/s
According to rate law
Rate of reaction=k[A]
If concentration of A is doubled then the rate of reaction is given by
Rate of reaction =k[2A]= 2 k[A]=2 initial rate of reaction
Therefore, rate of reaction after substituting values
Rate of reaction ==0.018 M/s
Rate of reaction when concentration of A is doubled=0.018 M/s.
Answer: constant of proportionality - the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
