What is the order of crystal violet reaction?
Introduction. The rate law for this reaction is in the form: rate = k[CV+]m[OH–]n, where k is the rate constant for the reaction, m is the order with respect to crystal violet (CV+), and n is the order with respect to the hydroxide ion.
What is the reaction order with respect the crystal violet?
The first order graph of crystal violet hydroxylation for both trails is a plot of natural logarithm of absorbance over time. The graph is linear with the higest R2 value of 0.99702 and 0.99801 for both trials. Thus, the order of reaction (m) with respect to crystal violet is first.
How do you find the order of a reaction from absorbance and time?
First Order: To see if the reaction is first order, it is necessary to plot a graph of the natural logarithm (ln) of absorbance vs. time. If this plot is linear, the reaction is first order. Second Order: To see if the reaction is second order, plot a graph of the reciprocal of absorbance vs.
How do you calculate rate of reaction from absorbance and time?
Reaction rate vs. absorbanceThe absorbance is directly proportional to the concentration, so this is simply a plot of the rate law, rate = k[C60O3], and the slope of the line is the rate constant, k.
What 4 factors affect the rate of a reaction?
There are four main factors that can affect the reaction rate of a chemical reaction:Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. Physical state of the reactants and surface area. Temperature. Presence of a catalyst.
What is the formula of time?
time = distance ÷ speed.
What are the four kinematic equations?
There are four kinematic equations when the initial starting position is the origin, and the acceleration is constant:v=v0+at. v = v 0 + at.d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.d=v0t+(at22)v2=v20+2ad.
What is the formula of time in simple interest?
Simple Interest Calculation Principal Amount remains constant during the entire tenure on Simple Interest. The formula for calculating Simple Interest is P x r x t ÷ 100, where P=Principal Amount, Rate of Interest & T= Time.
