What is used to describe the conditions of a reaction to equilibrium?
An equilibrium constant
Does a large equilibrium constant mean that the reaction must be rapid?
NO!!! A large Equilibrium Constant means that nearly all the reactants have been used up to reach the equilibrium. Conversely a small K(eq) indicates that equilibrium is reached when very little of the reactants have been used.
Describes chemical equilibrium?
Chemical equilibrium is a term used to describe a balanced condition within a system of chemical reactions. Essentially, when in chemical equilibrium, substances becomes definite and constant.
Why the reaction mixture doesn't have 50 percents reactants and 50 percents products at equilibrium position?
Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Take this example:2NO2(g) ↔N2O4(g)At this point of the reaction the rate of N2O4 produced from NO2 is the same as the rate of NO2 produced from N2O4. The key aspect to keep in mind is that the amounts (of moles) of products and reactants at equilibrium is not always 50%/50%. It is usually not.Finding the amounts of products and reactants present during a reaction can be found using Q. Q is known as the reaction quotient. Q can be found like so:Q=[products]/[reactants]reaction quotient =concentrations of products (M) / concentrations of reactantsQ is used to find this ratio at a certain point in time during a reaction (not atequlilibrium)Most likely, you will be given Keq, the equilibrium constant, for a reaction. The value tells you the concentrations of products/reactants at equilibrium. Comparing Q and Keqwill tell you whether a reaction is at equilibrium.Not to get off topic, the answer is that equilibrium does not mean that the reaction mixture has 50% reactants and 50% products. Equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.
What does Le Chatelier's principle state?
A reaction at equilibrium will respond to balance a change - apex (Explanation): The answer is NOT "a new equilibrium ratio will form", because although this is true, it will not necessarily always happen and is not what le chatelier's principle is about. His principle focuses on the reaction changing to cancel out or balance the change in equilibrium. Therefore, this is the correct answer.
What is used to describe the conditions of a reaction to equilibrium?
An equilibrium constant
What is used to describe the conditions at reaction at equilibrium?
At equilibrium the concentrations of reactants and productas remain constant.
What is used to describe the conditions of reaction at equilibrium?
At equilibrium the concentrations of reactants and productas remain constant.
Products and reactants are used and created at the same rate when a reaction is at this stage?
Dynamic equilibrium.
Does a large equilibrium constant mean that the reaction must be rapid?
NO!!! A large Equilibrium Constant means that nearly all the reactants have been used up to reach the equilibrium. Conversely a small K(eq) indicates that equilibrium is reached when very little of the reactants have been used.
When a chemical symbols and formulas are used as a shortcut to describe a chemical reaction is?
A chemical equation is used as a shortcut to describe a chemical reaction.
What is relaxatioin method in chemistry?
In chemistry, the term relaxation is used to describe a reaction's return to equilibrium and can be measured in temperature change, changes in the electronic filed, or a jump or drop in pressure. The RELAXATION METHOD is used to determine the RELAXATION TIME.

What term is used to describe when heat gain is equal to heat loss?
The term is "thermodynamic equilibrium."
What does it mean if arrows in a chemical reaction are the same length?
Two half arrows are usually used to denote a reaction which is in equilibrium. If they are the same length to one another then equilibrium is obtained and you have a mixture of reagent and product. If the arrow pointing right is larger then this denotes that the reaction is predominently a forwards reaction and favours the product and vice versa.
What word is used to describe a reaction in which energy is given out?
exothermic
