Unit 4 and Unit 5 Flashcards
What elements are not the precipitate
Na, K, NH4, NO3
What is determines the rate of a reaction
the frequency of collisions in molecules
what effects the rate of reactions (4 things)
Physical distribution
Concentration of the reactants
Temperature of Reaction
Catalyst
How to find the Activation Energy on a potential energy vs pathway graph
The E of A is from the reactant line to the top of the transition site
How to find the change in heat on a potential energy vs pathway graph
The change in heat is the energy of the products minus the energy of the reactants
What determines speed of a reaction based on a Eof A graph
The steepness of the peak, higher peak is a slower speed of reaction
When does K in rate law change
When temperature changes
What is a catalyst
Catalysts lower the activation energy and are used then reproduced
if 02 and n2 were compared in a gas state which would condense first and why
O2 becuase there are more elctrons therefore a stronger IMF of london dispersian forces so a higher polarizability causing o2 to condense first.
if concentration of A of a graph of concentration of reactant over time is linear what is the order
0 order
if concentration of natural log of A of a graph of concentration of reactant over time is linear what is the order
1 order
if concentration of 1/A of a graph of concentration of reactant over time is linear what is the order
2 order
