# What is the reaction order with respect to crystal violet concentration?

## What is the reaction order with respect to crystal violet concentration?

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.

## What sensor could we use to measure the concentration of the crystal violet over time?

Blocktronic spectrometer

## Which plot represents a second order reaction?

For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of −k. For a second-order reaction, a plot of the inverse of the concentration of a reactant versus time is a straight line with a slope of k.

## What is the pseudo rate law?

A very important case is that of pseudo-first order kinetics. This is when a reaction is 2nd order overall but is first order with respect to two reactants. The initial rate depends on both A and B and as the reaction proceeds both A and B are changing in concentration and affecting the rate. …

## Which among the following is an example of pseudo first order reaction?

Thus, the reaction appears to be first order, but it is actually of second order that’s why known as pseudo first order reaction. So, concentration of water can be approximated as constant as its concentration doesn’t change a lot during the reaction. thus, hydrolysis of cane sugar is pseudo first order reaction.

## What are pseudo first order reaction give one example of such reactions?

For example, the hydrolysis of esters by dilute mineral acids follows pseudo-first order kinetics where the concentration of water is present in large excess: CH3COOCH3 + H2O → CH3COOH + CH3OH. The hydrolysis of sucrose (C in acid solution is often cited as a first-order reaction with rate r = k[C.

## What is pseudo unimolecular reaction explain with example?

The reactions which look like second order reaction but behaves like first order reaction and follow first order rate law are called as pseudo unimolecular reactions. For example, acid hydrolysis of ester.

## What is half life period of reaction?

The half-life of a chemical reaction can be defined as the time taken for the concentration of a given reactant to reach 50% of its initial concentration (i.e. the time taken for the reactant concentration to reach half of its initial value).

## What is the half life period of first order reaction?

Half-life period of a first order reaction is 10 min.

## What is the half life period of a zero order reaction?

Since this is a zero-order reaction, the half-life is dependent on the concentration. In this instance, the half-life is decreased when the original concentration is reduced to 1.0 M. The new half-life is 80 seconds. Reaction B represents a zero-order reaction because the units are in M/s.

## What is meant by half life period?

Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive …

## What is the formula for calculating half life?

However, the half-life can be calculated from the decay constant as follows: half-life = ln (2) / (decay constant). To measure the decay constant, we take a sample of known mass and measure the number of radioactive decays per second as a function of time.
