conditions affecting chemical reactions Flashcards
1
Q
equilibrium
A
the stage of a chemical reaction in which both reactants and products are present, and their concentrations no longer change.
2
Q
factors that influence reaction rates
A
pressure, concentrations of reactants and products, temperature, and the presence of catalysts will change the speed of a reaction.
3
Q
catalyst
A
speeds up chemical reactions without undergoing permeant chemical change.
ex: enzymes
4
Q
endothermic reaction
A
absorption of heat
5
Q
exothermic reaction
A
release of heat
6
Q
Le Chatelier’s principle
A
a principle stating that when a chemical reaction at equilibrium is perturbed, it responds by proceeding in a direction that will restore the equilibrium.
7
Q
activation energy
A
the minimum energy needed to initiate a chemical reaction.
