How can you prove copper is a catalyst?
jolli1 [7]
There is no way to know which reaction requires which catalyst. However, if you apply copper to a reaction where it does act as a catalyst, the rate of reaction will be much faster as it lowers the activation energy for successful collisions.

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.

A mixture with medium sized particles that do not settle out is called
Alexandra [31]

Answer: colloid

Explanation:

Colloids are solutions in which small sized particles are suspended throughout the solution as they do not settle own their own. Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.

Colloids are solutions with particle size intermediate between true solutions and suspensions. Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily. The particle size in colloids is less and hence they do not settle under the effect of gravity.
