A multistep reaction can only occur as fast as its slowest step. Therefore, it is the rate law of the slow step that determines
kodGreya [7K]

Answer : The rate law for the overall reaction is, Rate=k[A][B]

Explanation :

Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

As we are given the mechanism for the reaction :

Step 1 : A+B\rightarrow AB    (slow)

Step 2 : A+AB\rightarrow A_2B     (fast)

Overall reaction : 2A+B\rightarrow A_2B

The rate law expression for overall reaction should be in terms of A and B.

As we know that the slow step is the rate determining step. So,

The slow step reaction is,

A+B\rightarrow AB

The expression of rate law for this reaction will be,

Rate=k[A][B]

Hence, the rate law for the overall reaction is Rate=k[A][B]

Why is the base of an energy pyramid wider than the top
Zepler [3.9K]

It is due to a lack of providable energy to the next trophic level of the energy pyramid. Primary consumers only obtain around 10% of energy that producers have, and the energy depletes as you move further and further up the food chain, until you reach the tertiary consumers which have the least amount of energy at their disposal, meaning there are less of them than other organisms further down the energy pyramid.


Hope this helped!

The heat of fusion for water is 80. cal/g. How many calories of heat are needed to melt a 35 g ice cube that has a temperature o
HACTEHA [7]

Answer: 2800 calories

Explanation:

Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure.

Amount of heat required to fuse 1 gram of water = 80 cal

Mass of ice given = 35 gram

Heat required to fuse 1 g of ice at 0^0C = 80 cal

Thus Heat required to fuse 35 g of ice =\frac{80}{1}\times 35=2800cal

Thus 2800 calories of energy is required to melt 35 g ice cube
