Answer : The rate law for the following mechanism is ![Rate=k'[A]^2[B]](https://tex.z-dn.net/?f=Rate%3Dk%27%5BA%5D%5E2%5BB%5D)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
As we are given the mechanism for the reaction :
Step 1 :
(fast)
Step 2 :
(slow)
Overall reaction : ![2A+B\rightarrow D](https://tex.z-dn.net/?f=2A%2BB%5Crightarrow%20D)
The rate law expression for overall reaction should be in terms of A and B.
As we know that the slow step is the rate determining step. So,
The slow step reaction is,
![C+A\rightarrow D](https://tex.z-dn.net/?f=C%2BA%5Crightarrow%20D)
The expression of rate law for this reaction will be,
............(1)
Now applying steady state approximation for
, we get:
![K=\frac{[C]}{[A][B]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BC%5D%7D%7B%5BA%5D%5BB%5D%7D)
...........(2)
Now substituting equation 2 in 1, we get:
![Rate=k[A]\times K\times [A][B]](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5Ctimes%20K%5Ctimes%20%5BA%5D%5BB%5D)
![Rate=K\times k[A]^2[B]](https://tex.z-dn.net/?f=Rate%3DK%5Ctimes%20k%5BA%5D%5E2%5BB%5D)
![Rate=k'[A]^2[B]](https://tex.z-dn.net/?f=Rate%3Dk%27%5BA%5D%5E2%5BB%5D)
Hence, the rate law for the following mechanism is ![Rate=k'[A]^2[B]](https://tex.z-dn.net/?f=Rate%3Dk%27%5BA%5D%5E2%5BB%5D)

Answer:
103.00
Explanation:
1 mole of Glucose
6 C = 6 * 12 = 72 grams
12H = 12 * 1 = 12 grams
6O = 6 * 16 =96 grams
Total = 180 grams
0.572 moles of Glucose
1 mol of glucose = 180 grams
0.572 mols of glucose = x
x = 0.572 * 180
x = 103.00 grams
Your pattern of breathing increases, making it faster than usual, when you're exercising because you're pushing your body to work harder and speeding up your heart rate making you tired.
When you're resting your breathing pattern should be steady and normal since you aren't doing anything that requires lots of body work or something that would make you out of breath.
Hope this helps,

PH is a measure of the concentration of H+ ions are free in solution. It is defined as pH = -log([H+]).
If you replace pH with y and [H+] with x, you get the function y = log(x). If you analyze how this function changes as you increase x, this will show you how pH varies as X changes. Remember, H+ makes a solution more acidic!
