Explain why the catalyst is used as a very fine powder and larger pieces of iron are not used.

Chemistry

Allushta [10]3 years ago
7 0

Answer:

<h2><u>Reason:</u></h2>

Catalyst is used as a very fine powder and larger pieces of iron are not used. This is because the surface area of catalyst needs to be large so that more of the surface is exposed to the substrate and more of the substrate is catalyzed.

<h2><u>Important Info:</u></h2>

=> Larger Pieces of Iron has a smaller surface area than the fine particles.

=> Larger the surface area of catalysts/enzymes , more will be the reaction rate and vice versa.

Hope this helped!

A student pipets 10 ml of a 0.0693 m solution of kbr into a 500 ml volumetric flask and dilutes to the mark. what is the concent
Sonja [21]

The initial concentration of solution is 0.0693 M. The volume of solution taken is 10 mL and it is diluted to a final volume of 500 mL.

According to dilution law, the product of initial concentration and volume is equal to the product of final concentration and volume as follows:

C_{1}V_{1}=C_{2}V_{2}

Here, C_{1} is initial concentration, C_{2} is final concentration, V_{1} is initial volume and V_{2} is final volume.

Rearranging to calculate final concentration,

C_{2}=\frac{C_{1}\times V_{1}}{V_{2}}

Putting the values,

C_{2}=\frac{0.0693 M\times 10 mL}{500 mL}=0.001386 M

Therefore, concentration of the resulting solution is 0.001386 M.

kolbaska11 [484]

Answer:

Exothermic Reactions.

Explanation:

Reactions that release energy are called exothermic reactions.

Whereas that absorb energy are called Endothermic reactions.

More energy is being released to the surroundings than was absorbed to initiate and maintain the reaction in case of exothermic reactions.

Burning of a candle is an exothermic reaction.
