Which of these figures probably shows a sugar solution containing a small amount of sugar dissolved in water
2 answers:
Answer:
The correct answer is B.
Explanation:
I had to look at the images to know what options I had. Sugar is soluble in water, so it has a saturation point at which it precipitates as a solid into a solution containing a large amount of sugar. If the amount is small, the sugar dissolves completely and no particles are observed in the solution.
Have a nice day!

Answer : The value of rate of reaction is
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.
The given chemical equation is:
Rate law expression for the reaction is:
As per question,
a = order with respect to = 2
b = order with respect to = 1
Thus, the rate law becomes:
Now, calculating the value of rate of reaction by using the rate law expression.
Given :
k = rate constant =
[NO] = concentration of NO =
= concentration of
=
Now put all the given values in the above expression, we get:
Hence, the value of rate of reaction is
