In the hydrogenation of ethylene using a nickel catalyst, the initial concentration of ethylene is 2.00mol?L?1 and its rate cons
gavmur [86]

Answer:

The rate of reaction of a zero-order reaction  is 0.0020 mol/L.

Explanation:

The rate expression of the zero order kinetic are :

R=k[A]^o

[A]= initial concentration of reactant

k = rate constant

R = rate of reaction

We have :

Rate constant of the reaction , k = 0.0020 mol/L s

R=0.0020 mol/L s\times 1

R = 0.0020 mol/L s

The rate of reaction of a zero-order reaction  is 0.0020 mol/L.

Enter the net ionic equation representing aqueous acetic acid neutralized by aqueous barium hydroxide.
IrinaK [193]

Answer:

The answer to your question is below

Explanation:

Data

Aqueous acetic acid

Aqueous barium hydroxide

Formula

Acetic acid    CH₃CH₂COOH

Barium hydroxide   Ba(OH)₂

Neutralization reaction

        CH₃CH₂COOH    +    Ba(OH)₂      ⇒  Ba( CH₃CH₂COO)₂ + H₂O

                                                                    Barium acetate + H₂O

Barium acetate =  Ba( CH₃CH₂COO)₂ = Ba(C₃H₅O₂)₂
