To solve this we need to have knowledge of differential rate law which relate the rate to the concentration and time. Therefore, the rate of overall reaction is 1x10⁻²M/s.
<h3>
What is differential rate law? </h3>
A differential rate law represents the rate of a reaction . According to this rate is directly proportional to changes in the concentration of reactants and inversely proportional to specific interval of time. There is another expression of rate law which is integrated rate law which is just opposite of differential rate law.
The given equation is
2NO + O 2NO
(1/2) Rate of disappearance of NO= rate of disappearance of C= (1/2)rate of appearance of NO= rate of overall reaction.
(1/2)rate of appearance of NO= rate of overall reaction.
rate of appearance of NO=2x10⁻²M/s.
Substituting the values in above equation
(1/2)×2x10⁻²M/s = rate of overall reaction.
rate of overall reaction= 1x10⁻²M/s
Therefore, the rate of overall reaction is 1x10⁻²M/s.

Answer : The number of moles of added must be, 0.37 mol
Explanation :
The given chemical reaction is:
Initial mol. 2.99 x 0 0
At eqm. (2.99-1.30) (x-1.30) 1.30 1.30
= 1.69
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
x = 1.67 mol
The moles of added = (x-1.30) = (1.67-1.30) = 0.37 mol
In order from the number of protons in its atomic nucleus

Entropy is the degree of disorderliness in a system. Among the phases, solid
has the most ordered structure. Therefore, the lowest entropy. The least ordered is the gas phase which represents the highest entropy. Therefore, the correct answer is option D, steam. </span>
