Many chemical reactions, like combustion , go to completion and not to equilibrium. It is normally desirable to give a chemical reaction time to reach equilibrium in order you get the maximum yield of one or more products.

What does it mean for a reaction to be a equilibrium?
In a particular time, if the forward and backward reactions of a reversible reactions take place in the same rate, there would be not a visible change (i.e. no net change) in the system, and that system is said to be at equilibrium.
What kind of chemical reaction needs to take place so that methanol can be synthesized?
The most common reaction is:CO + 2 H2 = CH3OH
What reaction takes places in the thylakoid disc of the chloroplast?
Light reaction takes place. The first step of photosynthesis
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
What is the amount of energy a reaction needs to take place?
The amount of energy a reaction needs to take place is called activation energy. When this much energy is present, a chemical reaction can occur.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.

What are the advantages of using catalysts?
Catalysts can do one or more of the following:enable a chemical reaction to take place,speed up the reaction,allow the reaction to proceed at a lower temperature,change the equilibrium point of a reversible reaction so that more of the desired output is produced.
What information does the rate constant give the rate law?
It tells how much the reaction rate is affected by concentrations.
What is the opposite of a reaction releasing energy?
A reaction releasing energy is called an exergonic reaction, so the opposite of the would be a reaction that needs energy to take place, called an endergonic reaction. These are also known as exothermic and endothermic reactions.
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.
When does photosynthesis accur?
Light reaction take place in day time. Dark reaction take place at night
What reaction takes places in the thylakoid disc of the chloroplast?
Light reaction takes place. The first step of photosynthesis
What type of reaction take place in rancidity?
chemical reaction takes place in rancidity
Does the reaction between non-metals and acid take place?
no reaction takes place
