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
Hope this Helps!!!
<u>0.4 mol of </u> molecules has larger mass than 0.4 mol of O atoms
The smallest component of a substance that possesses both its chemical and physical characteristics. One or more atoms make up molecules.
They may have the same atoms (for example, an oxygen molecule has two oxygen atoms) or different atoms if they have more than one (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules like DNA and proteins can include thousands of atoms.
the lowest recognised unit into which a pure material can be divided while retaining its chemical makeup and attributes is made up of two or more atoms.
