25
Why does increase in temp speed up rxn?
More Collisions
26
Is heterogenous or homogenous rxn faster?
Homogenous, as in heterogenous, the rxn can only happen where the states mix
27
Do reaction orders depend on stoichiometry
NO!
28
Why does higher concentration increase rxn speed?
More Collisions!
29
Why do catalysts increase rxn speed?
Lowers the activation energy
| by changing the rxn mechanism
30
Which step is rate limiting?
The slow one, this dictates overall rxn order
31
Can a mechanism be proven?
NO!
32
Number of protons in an Atom
Atomic Number
33
for element Q with atomic number i, how many protons and electrons does it have?
yxQ
i - x protons
y electrons
34
What kind of kinetics does nuclear decay follow?
First Order
