what i need to know for chem Flashcards
Structural isomer:
Organic molecules with the same molecular formula, but different structural formulae
heat of reaction
the energy absorbed or released in a chemical
reaction.
activation energy
as the minimum energy needed for a reaction to take place.
activated complex
as the unstable transition state from reactants to products.
reaction rate
the change in concentration of reactants or products per unit
time.
catalyst
a substance that increases the rate of a chemical reaction without itself undergoing a permanent change.
Open and closed systems:
An open system continuously interacts with its
environment, while a closed system is isolated from its surroundings.
A reversible reaction:
A reaction is reversible when products can be converted back to reactants and vice versa.
State Le Chatelier’s principle:
When the equilibrium in a closed system is disturbed, the system will re-instate a new equilibrium by favouring the reaction that will oppose the disturbance.
Concentrated acids/bases
contain a large amount (number of moles) of acid/base in proportion to the volume of water.
Saturated compounds:
Compounds in which there are no multiple bonds
between C atoms in their hydrocarbon chains
Unsaturated compounds:
Compounds with one or more multiple bonds between C atoms in their hydrocarbon chains
