What is a cat in chemistry?
Catalytic (cat.; catalytic amount): The reactant in question is a catalyst, or present in small amount. A catalytic converter for an internal combustion engine contains a small (catalytic) amount of a platinum group metal to catalyze the oxidation of carbon monoxide into carbon dioxide.
What is an order in chemistry?
The order of a chemical reaction is defined as the sum of the powers of the concentration of the reactants in the rate equation of that particular chemical reaction.
What is the order of a reactant?
The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant. Thus, for a first-order reaction, the rate is dependent on the concentration of a single species. The order of reaction is an experimentally determined parameter and can take on a fractional value.
Why does cat urine smell so bad?
Cat pee consists of urea, urobilin/urobilinogin, uric acid, sodium, other electrolytes, creatinine, pheromones and bacteria. The first step in the decomposition of the pee, is bacteria breaks down the urea (which is actually odorless) releasing ammonia, hence the strong ammonia scent associated with your litter box.
Do kittens produce Fel d 1?
Kittens produce less Fel d 1 than adult cats. Female cats produce a lower level of Fel d 1 than (unneutered) males, while neutered males produce levels similar to those of females. Both intact and spayed females produce similar levels.
Can order be fractional?
The order can be a positive integral value which indicates that the rate of the reaction is affected directly by the concentration of the reactants. The order can also be equal to a fractional value. It indicates an intricate relationship between the rate of the reaction and the concentration of the reactants.
How do you find the order of a reaction?
The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2.
What is a 2nd order reaction?
Definition of second-order reaction : a chemical reaction in which the rate of reaction is proportional to the concentration of each of two reacting molecules — compare order of a reaction.
What is 2st order reaction?
A second order reaction is a type of chemical reaction that depends on the concentrations of one-second order reactant or two first-order reactants. This reaction proceeds at a rate proportional to the square of the concentration of one reactant, or the product of the concentrations of two reactants.
Do male cats smell worse than females?
Older animals have kidneys that have lost some of their efficiency and as a consequence, older animals tend to have the worst smelling urine. Urine from male cats also tends to smell worse than female urine, due to the presence of certain steroids.
