Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out necessary for us remember that the first-order kinetics is given by:
Whereas the 27.5% complete means A/Ao=0.275, and thus, we solve for the rate constant as follows:
Then, we plug in the variables to obtain:

Answer:
- 0.36 m/s.
Explanation:
- For the reaction: <em>a + 2b → c,</em>
<em>∵ The initial rate of the reaction = - δ[a]/δt = - 1/2 δ[b]/dt = 0.180 m/s.</em>
∴ The initial rate of the reaction = - 1/2 δ[b]/dt = 0.180 m/s.
∴ - 1/2 δ[b]/dt = 0.180 m/s.
<em>∴ δ[b]/dt </em>= (- 2)(0.180 m/s) =<em> - 0.36 m/s.</em>
The measure of how much solute is mixed in with a solvent is called concentration. It's how much solute was put into the solvent (most likely water) <span />
Answer: 50.9g of Fructose
Explanation:
No of moles = Mass (g) / Molar Mass (g/mol)
Moles = 0.283
Molar Mass of Fructose (C6H12O6) = 12 x 6 + 1 x 12 + 16 x 6 = 180g/mol
Mass = ?
Make 'Mass' the subject of formular, we will have;
Mass = Molar Mass x No of moles
= 180g/mol x 0.283
= 50.9g of Fructose
