What are the characteristics of equilibrium constant class 11?
It has a definite value for every chemical reaction at a particular temperature. It is independent of the initial concentrations of the reacting species. It changes with the change in the temperature. It depends on the nature of the reaction.
What are the characteristics of equilibrium?
What is equilibrium constant class 11?
What does the equilibrium constant characterize?
What are characteristics of K?
What is called redox reaction explain with example?
An oxidation-reduction reaction is any chemical reaction in which, by obtaining or losing an electron, the oxidation number of a molecule, atom, or ion varies. An example of a redox reaction is the formation of hydrogen fluoride. To study the oxidation and reduction of reactants, we should break the reaction down.
What affects KP?
Kc, Kp and the position of equilibrium are affected by temperature in endothermic and exothermic equilibria. The effects are the same as predicted by Le Chateliers principle. Exothermic reactions: Temperature rise: – position of equilibrium moves to left, Kp and Kc become smaller.
What does a catalyst do to the activation energy required to start a reaction?
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.
What is r in biology?
r is for reproduction. Such a species puts only a small investment of resources into each offspring, but produces many such low effort babies. Such species are also generally not very invested in protecting or rearing these young. Often, the eggs are fertilized and then dispersed.
What is an R species?
r-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). Such species make up one of the two generalized life-history strategies posited by American ecologist Robert MacArthur and American biologist Edward O.
Why is redox learning important?
Redox reactions take us down an important conceptual pathway in chemistry. Our understanding of redox begins with the gain and loss of oxygen and develops into the gain and loss of hydrogen. This paves the way to understanding all chemical reactions as a rearrangement of electrons.
What is the difference between displacement and double displacement reaction?
Solution : In a displacement reaction, a more reactive element replaces a less reactive element from a compound <br> For Example : `CuSO_(4)(aq)+Zn(s) rarr ZnSO_(4)(aq) + Cu(s)` <br> In a double displacement reactions, two atoms or a group of atoms switch places to form new compounds <br> For Example : `Na_(2)SO_(4)(aq …

- C stands for the change in concentration. …
- E is for the concentration when the reaction is at equilibrium.

What is r in chemistry?
R is an abbreviation for radical, when the term radical applied to a portion of a complete molecule (not necessarily a free radical), such as a methyl group.

How do you know if an equation is balanced?
If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
How do I figure out how much catalyst I need?
catalyst wt(g) / R1 (g) + R2(g) + Catalyst wt(g) = wt % of catalyst used in the reaction.
What determines how much product can form in a chemical reaction?
Summary. The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
What is a K-selected species?
K-selected species possess relatively stable populations fluctuating near the carrying capacity of the environment. These species are characterized by having only a few offspring but investing high amounts of parental care. Elephants, humans, and bison are all k-selected species.
