rate = k[A], k= rate constant / of proprotion , [] =concentration. (@ = change in []concentration ,@t change in time)
a A +bB-> cC from this the rate = -1/a(@[A]/@t) =-1/b(@[B]/@t) =1/c(@[C]/@t where the small letters are the coefficents . so the rate of a reaction is equal to each other when ajusted by the coeffiects . note that the reactants are negative becasue it is decreasing as products form..
the basic difference of a fist order and a second is proportions.. fist is directly proportional id est concentration goes up by 2 the rate goes up by two.
while second is proportional to the square.
concentration goes up by two the rate goes up by 4
1. First-Order Reactions
A first order reaction (order = 1) has a rate proportional to the concentration of one of the reactants. A common example of a first-order reaction is the phenomenon of radioactive decay. The rate law is:
rate = k[A] (or B instead of A), with k having the units of sec-1
2. Second-Order Reactions
A second-order reaction (order = 2) has a rate proportional to the concentration of the square of a single reactant or the product of the concentration of two reactants:
rate = k[A]2 (or substitute B for A or k multiplied by the concentration of A times the concentration of B), with the units of the rate constant M-1sec-1
If the rate of the reaction depends upon both the reactants.. wrong!
A second order reaction yields the rate proprontional to the square of the concentration. id est the concentration goes up by 2 : the rate goes up by 4
for the former to be correct, both reactants must be of the first order becasue the over all order is determined by adding the value of [ A]^ n & [B]^ m
The first one (you are stubborn) is an opinion statement. The second one is a factual statement.
source of illuminatio is light in first and beam of electrons in second
A zero-order reaction is a reaction that proceeds at a rate that is independent of reactant concentration. Typically with increasing or decreasing reactants
The reaction site of the first and second steps of aerobic respiration is called the matrix. Aerobic respiration occurs inside a Golgi body.
The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneous.
Difference between first shifting and second shifting theorem
what is the difference between first and second class proteins

A second alto has a wider range in the lower register than a first alto has.
Yes. The first is a speed (or velocity), the second is a distance.
To find the difference between two numbers, just subtract the second from the first.8.4-6.3=2.1
