Answer:

The rate of a chemical reaction is directly proportional to the concentration. The rate of a chemical reaction increases as the substrate concentration increases and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.

Explanation:

The rate of a chemical reaction is directly proportional to the concentration.

The reaction rate increases with increasing substrate concentration, but levels off at a much lower rate. By increasing the enzyme concentration, the maximum reaction rate greatly increases.

Generally, the rate of a chemical reaction increases as the substrate concentration increases, and thus, concentration of the substrate in an enzyme-controlled chemical reaction increases with time.

Answer:

The substrate concentration decreases rapidly until a saturation point is reached where there is no further change in substrate concentration.

Explanation:

One of the most important parameters in discussion of rate of enzyme catalysed reaction is the substrate concentration. The rate of reaction increases smoothly as the rate of reaction until a point is reached and the rate of reaction becomes independent of substrate concentration. This is the saturation point.

A chemical engineer has determined by measurements that there are 69.0 moles of hydrogen in a sample of methyl tert-butyl ether.

Juli2301 [7.4K]

5.75 moles The formula for methyl tert-butyl ether is (CH3)3COCH3, so a single molecule has 5 carbon, 12 hydrogen, and 1 oxygen atoms. So for every 12 moles of hydrogen, there's 1 mole of oxygen. So simply divide the number of moles of hydrogen by 12 to get the number of moles of oxygen. 69.0 / 12 = 5.75 Therefore there's 5.75 moles of oxygen in the sample.

Chlorination of alkanes can produce a multitude of products. Determine the number of monochlorinated and dichlorinated products

ArbitrLikvidat [17]

Answer:

monochlorinated products: 4

dichlorinated products: 12

Explanation:

Chlorination of alkanes is a reaction that takes place when the chlorine is in presence of light. This actually decomposes the chlorine, and one atom of Chlorine substracts an hydrogen from the alkane. Now, this hydrogen substracted comes usually from the most substitued carbon, because it's more stable (A tertiary carbon is more stable than a secondary carbon, and this more stable than primary).

When this happens, the other chlorine atom, goes as electrophyle in that carbon and formed the chlorinated product. Now, although a tertiary carbon is more stable, we can still have (in minor quantities) chlorinated products that comes from a secondary and primary carbon. The first picture shows the general mechanism of the chlorination, and the possible products for a monochlorinated.

The second picture shows the possible dichlorinated products, which are in higher quantities than the monochlorinated basicallu because of the variety of positions the chlorine can be. So, second picture shows all the products.
