Select all of the correct statements about reaction rates from the choices below

Question

Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step. A balanced chemical reaction is necessary to relate the rate of disappearance of a reactant to the rate of appearance of a product. A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. Slow reactions can be speeded up by raising the temperature. Concentrations of homogeneous catalysts have no effect on reaction rates. Reaction rate constants decrease with increasing temperature.

Explanation / Answer

Select all of the correct statements about reaction rates from the choices below.

The lower the rate of a reaction the longer it takes to reach completion.--------CORRECT

=========================================================================

The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step.-INCORRECT

======================================================================================

A balanced chemical reaction is necessary to relate the rate of disappearance of a reactant to the rate of appearance of a product. .--------CORRECT

A balanced chemical reaction is necessary to relate the rate of reaction to the concentration of a reactant. -CORRECT

============================================================

Slow reactions can be speeded by by raising the temperature-CORRECT

Concentrations of homogeneous catalysts have no effect on reaction rates----INCORRECT

Reaction rate constants increase with increasing temperature. -CORRECT

Temperature: When you raise the temperature of a framework, the atoms skip around significantly more. They have more vitality. When they skip around additional, they will probably impact. That reality implies they are likewise more prone to consolidate. When you bring down the temperature, the particles are slower and impact less. That temperature drop brings down the rate of the response. To the science lab! In some cases you will blend arrangements in ice so that the temperature of the framework remains cool and the rate of response is slower.

Pressure: Pressure influences the rate of response, particularly when you take a gander at gasses. When you increment the weight, the atoms have less space in which they can move. That more prominent thickness of atoms expands the quantity of impacts. When you diminish the weight, atoms don't hit each different as regularly and the rate of response reductions.
