Calculate the average reaction rate expressed in moles h2 consumed per liter per second
1 answer:
Answer:
Average rate of reaction expressed in moles H₂ consumed per liter per second = 0.0025 M/s = 0.0025 mol/L.s
Explanation:
The complete, correct Question, is presented in the attached image to this answer.
The average rate of reaction in terms of the reactant is defined as the total amount of reactant consumed over a period of time divided by total period of time.
Mathematically,
Average rate of reaction = (change in concentration of H₂ over a period of time) ÷ (total period of time)
Average rate of reaction = (-ΔC)/(Δt)
The minus sign is there because the concentration of reactants reduce with time.
change in concentration of H₂ = -ΔC
= -(0.02 - 0.03) = 0.01 M
Time = Δt = 4 - 0 = 4.0 s
Average rate of reaction = (0.01/4) = 0.0025 M/s
We could solve for the average rate of reaction expressed in moles Cl₂ consumed per liter per second
change in concentration of Cl₂ = -ΔC
= -(0.04 - 0.05) = 0.01 M
Time = Δt = 4 - 0 = 4.0 s
Average rate of reaction = (0.01/4) = 0.0025 M/s = 0.0025 mol/L.s

<u>Answer:</u> The volume of water required is 398 mL
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
We are given:
Mass of solute (manganese (II) nitrate tetrahydrate) = 16 g
Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol
Molarity of solution = 0.16 M
Putting values in above equation, we get:
Hence, the volume of water required is 398 mL
The chemical formula of oxalic is
When oxalic acid reacts with water, first, oxalic acid removes one proton and results in the formation of mono acids.
After that, in second step, oxalic acid in aqueous solution removes another proton which shows it is a polyprotic acid.
The chemical equations are: (the reactions occurs in two steps due to presence to hydrogen atoms).
When one proton is removed:
When another proton is removed:
The dissociation of oxalic acid in water in shown in the image.
