Answer:
Centimeters per minute
Explanation:
Speed measurement is formated as [distance] per [time], like miles per hour.
B and C are incorrect because they are [time] per [distance]
A is incorrect because it is [time] per [time]
Answer : The rate law for the following mechanism 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.
As we are given the mechanism for the reaction :
Step 1 : (fast)
Step 2 : (slow)
Overall reaction :
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,
The expression of rate law for this reaction will be,
............(1)
Now applying steady state approximation for , we get:
...........(2)
Now substituting equation 2 in 1, we get:
Hence, the rate law for the following mechanism is
Answer:
Protein Concentration is 2.82mg/L
Explanation:
According to Beer-Lambert's Law, Absorbance is directly proportional to the concentration.
However, the concentration of a solution can be determined from a calibration curve, in which Absorbance is plotted on the y-axis and the Concentration on the x-axis.
Plotting the best line, the equation of line is used
y = mx + c
where y is absorbance = 0.150
m is slope = 0.0163
x is concentration
c is intercept = 0.104
inserting the values from the question
y = mx + c
0.150 = 0.0163x + 0.104
0.0163x = 0.150 - 0.104
0.0163x = 0.046
Divide both sides by 0.0163
0.0163x/0.0163 = 0.046/0.0163
x = 2.82
Concentration of protein = 2.82 mg/L
Answer:
The same element that contain equal number if protons but different number of neurons in their nuclei and hence differ in relative atomic mass
