These compounds do not spontaneously react at room temperature.
thermodynamically stable
a reaction in which the products turn back into the original reactants
reversible reaction
What 5 factors affect reaction rates?
temperature, concentration, nature of reactants (ionic, covalent), catalysts and inhibitors, surface area
These reactions do react spontaneously but at a rate so slow that it is undetectable.
kinetically stable
the energy required to form an activated complex
activation energy
a temporary compund formed by the coming together of high energy reactants
activated complex
the process of increasing reaction rates by using a catalyst
An inhibitor slows down the reaction by decreasing the __________ of that reactant.
The reaction between __________ compounds take longer than reactions between _________ substances in a solution.
covalent, ionic
A reaction in which the reactants are forming products at the same rate the products are turning back into the reactions is said to be in ____________.
a substance that speeds up a reaction without itself being permanently changed by the reaction
Catalysts work by ________________________.
lowering the required activation energy of a reaction.
Reaction in which all the reactants are in the same phase
