Answer:
17.2 minutes is the value of the turnover number.
Explanation:
Using Michaelis-Menten equation:
![V = V_{max}\times \frac{[S]}{ (Km + [S])}](https://tex.z-dn.net/?f=V%20%3D%20V_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%20%28Km%20%2B%20%5BS%5D%29%7D)
Where :
= max rate velocity
[S] = substrate concentration
= Michaelis-Menten constant
V = reaction rate
= catalytic rate constant
= initial enzyme concentration
We have :
is the rate is obtained when all enzyme is bonded to the substrate. is termed as the turnover number.
17.2 minutes is the value of the turnover number.
Answer:
(a) rate = 4.82 x 10⁻³s⁻¹ [N2O5]
(b) rate = 1.16 x 10⁻⁴ M/s
(c) rate = 2.32 x 10⁻⁴ M/s
(d) rate = 5.80 x 10⁻⁵ M/s
Explanation:
We are told the rate law is first order in N₂O₅, and its rate constant is 4.82 x 10⁻³s⁻¹ . This means the rate is proportional to the molar concentration of N₂O₅, so
(a) rate = k [N2O5] = 4.82 x 10⁻³s⁻¹ x [N2O5]
(b) rate = 4.82×10⁻³s⁻¹ x 0.0240 M = 1.16 x 10⁻⁴ M/s
(c) Since the reaction is first order if the concentration of N₂O₅ is double the rate will double too: 2 x 1.16 x 10⁻⁴ M/s = 2.32 x 10⁻⁴ M/s
(d) Again since the reaction is halved to 0.0120 M, the rate will be halved to
1.16 x 10⁻⁴ M/s / 2 = 5.80 x 10⁻⁵ M/s
Answer:
sound waves travel.faster through materials that are more dense
C. Ca and Br because they're metals and nonmetals
Newton's F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a)
Explanation:
F = ma, or force is equal to mass times acceleration.
