The correct answer is C) There are more particle collision
With more particle collision, more reactions are created.
Answer:
option C= hydrolysis and break down
Explanation:
All other three pairs are correct coupling of each others.
Option A= dehydration synthesis and hydrolysis
Dehydration synthesis:
In dehydration synthesis monomers combine through the covalent bonds and form large molecules. The large molecules are called polymers. The water as a byproduct also released when monomers joints together.
Hydrolysis:
In hydrolysis the polymers are break down into monomers by using water molecules. The catalysts are also required in this process.
Option B= Catabolic and Anabolic
Anabolic:
In this process smaller molecules combine to gather to form large complex molecules by using energy.
For example simple glucose molecules join together to form large disaccharides.
Catabolic:
It is the break down of large complex molecules to the smaller molecules.
For example during cellular respiration sugar molecules break down and generate energy.
Option D= Break down and synthesis
The break down and synthesis are also reverse pair of each others. The synthesis involve the formation of molecules form smaller component while the break down involve destruction of molecules into smaller units.
Answer:
D
Explanation:
D. The number of moles of a dissolved substance
Answer:
Rate: R = k [A]²
Explanation:
The rate law equation for a given complex chemical reaction is given as the product of molar concentrations of the reactant raised to the power their respective partial reaction orders. The sum of the partial reaction orders is equal to the overall order of reaction.
For a complex reaction, the rate law is generally determined by the slowest step, which is known as the rate-determining step.
<u>Given reaction mechanism:</u>
Step 1: 2 A⟶ B, slow step
Step 2: B+ C⟶ D, fast step
Overall: 2 A + C ⟶ D
In this given reaction mechanism, the <em>step 1 is the slow step and thus the rate determining step.</em>
Therefore, the rate law for the given mechanism is:
Rate: R = k [A]²
Here, k is the overall rate constant
Also, the overall order of the reaction = 2
Therefore, the given chemical reaction is said to be second order reaction.
