Answer : The correct expression for equilibrium constant will be:
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,
I am answering this question with respect to organic molecules in proteins. In case of proteins, the sequence of proteins (order) greatly affects the function of protein.For example, in enzymes the binding site or catalytic site has a catalytic residues (organic molecules = amino acids) at specific positions. And these amino acids together catalyzes the reaction. Like Serine, Histidine and Aspartic in chymotripsin together catalyzes the hydrolysis of protein and they have specific order (i.e serine 195, histidine 57 and aspartic acid 102. So, order is very important in functionality of protein.
Secondly, the shape is very important. Like, in above example the -OH group of Asp protonates the carbonyl groups in substrate, the -OH group of Ser acts as a nucleophile and the -NH group of His acts as a base by abstracting the protons during the reaction. So, it is the shape of these amino acids which are helping in functioning the enzyme.
So, the correct answer is Order and Shape.
Answer:
<em>One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.</em>
Answer:
7.2 gm or 0.0072 Kg
Explanation:
Let k be the kg of packets that are to be used.
36 X 200 mg = 1000 X k
=> k = 7.2 gm.
