Answer:
The reaction rate is inversely proportional to the reaction time.
Explanation:
- The reaction rate is the change of the concentration of reactants and products with the time.
<em>∵ Reaction rate = - Δ[reactants]/Δt = Δ[products]/Δt.</em>
<em>∴ The reaction rate is inversely proportional to the time, as the reaction rate increases it will take a lower time.</em>
Answer : The concentration of
(g) in parts per million is, 8 ppm
Explanation : Given,
Mass of oxygen gas (solute) = 0.008 g
Mass of water (solvent) = 1000 g
First we have to calculate the mass of solution.
Mass of solution = Mass of solute + Mass of solvent = 0.008 + 1000 = 1000.008 g
Now we have to calculate the concentration of
(g) in parts per million.
ppm : It is defined as the mass of solute present in one million
parts by mass of the solution.

Now put all the given values in this expression, we get

Therefore, the concentration of
(g) in parts per million is, 8 ppm
