How the Nature Of Reactants Affects Rate of Reaction - Ionic/Covalent Reactions Flashcards
Reactions involving what type of substances are generally fast?
Ionic substances
At what speed do reactions involving ionic substances occur?
They occur generally fast
What is an example of a reaction between ionic substances?
The reaction between solutions of silver nitrate and sodium chloride
What type of substances are the solutions of silver nitrate and sodium chloride?
They are both ionic substances
What type of reaction takes place between the two ionic substances of silver nitrate and sodium chloride?
An instantaneous reaction occurs
Why do ionic substances have a fast rate of reaction?
As when an ionic compound dissolves in water the bods between the ions in the compound are broken by the water, these ions now only need to come together to complete the reaction
What happens when an ionic compound is dissolved in water?
The bonds between ions in the compound are broken
When ionic compounds are dissolved in water what is it that breaks the bonds between the ions of the compound?
Water breaks these bonds
How is the reaction completed when an ionic compound is dissolved in water?
Ions from the broken bonds of the compound must come together to complete the reaction
At what speed does the rate of reaction between covalent substances occur?
The reaction is slower than that of an ionic substance
Why are covalent reactions slower than ionic reactions?
As covalent bonds must first be broken down
What must first be done to covalent bonds before a covalent reaction can take place?
The covalent bonds must first be broken down
Where do reactions of ionic compounds usually take place in?
Aqueous solution
Why must covalent bonds by broken down before a reaction between covalent compounds is carried out?
As the covalent bonds must be broken down in order for new bonds to be formed during the reaction
