2024/2025 Comprehensive Questions A+ Graded Answers | With Expert Solutions
Alkanes - nonpolar
saturated
CnH2n+2
Methane - 1 C
Ethane - 2 C
Propane - 3 C
Butane - 4 C
Pentane - 5 C
Hexane - 6 C
Heptane - 7 C
Octane - 8 C
Nonane - 9 C
Zero-order graph - Concentration vs. time
1st-order graph - ln[A] vs. time
, 2nd-order graph - 1/[A] vs. time
Units of K for 0th order - M/s
Units of K for 1st order - 1/s
Units of K for 2nd order - M-1 S-1
K>>1 - product-favored
K<<1 - reactant-favored
Q = K - equilibrium
Q > K - proceeds right to left
need to produce more reactants
Q < K - proceeds left to right
need to product more products
H > 0 - Endothermic (heat is a reactant)
H < 0 - Exothermic (heat is a product)
Endothermic rxns - ^T ^K
Decrease heat = rxn shifts to the left; K decreases
Exothermic rxns - Increase heat = rxn shifts to the left; K decreases
Decrease heat = rxn shifts to the right; K increases
