EXAMINATION PAPER 2026 QUESTIONS
WITH ANSWERS GRADED A+
⩥ Speed of light relationship: Answer: c=λf
⩥ Photon energy (combined): Answer: E=hc/λ
⩥ what is light constant "c" = to Answer: 3x10^8
⩥ Planck's constant Answer: 6.626 x 10^-34
⩥ Find energy change from one orbital to another Answer: R=[1/(ni^2)-
1/(nf^2)]
⩥ maximum number of electrons in a given shell Answer: 2n^2
⩥ Density: Answer: ρ=m/v
⩥ Molarity: Answer: moles of solute/liters of solution
,⩥ Molality: Answer: moles of solute/kg of solvent
⩥ Osmolality Answer: i (van't hoff factor) x M
⩥ van't Hoff factor Answer: - total # of of particles in solution
- Ex: glucose is 1
- Ex: NaCl is 2 (breaks up into 2 ions)
⩥ Ideal gas law: Answer: PV=nRT
⩥ Dalton's law of partial pressures: Answer: Ptotal=∑Pi
⩥ Partial pressure from mole fraction: Answer: Pi=Xi(Ptotal)
⩥ Vapor pressure (Raoult's Law): Answer:
Psolution=Xsolvent(Psolvent)
⩥ Boiling point elevation: Answer: ΔTb=iKbm
⩥ Freezing point depression: Answer: ΔTf=iKfm
, ⩥ Heat transfer: Answer: q=mcΔT
⩥ Phase change heat: Answer: Q = mL or q=nΔH
⩥ Enthalpy change (if given bond dissociation E) and standard change
in enthalpy Answer: ΔH= total E of bonds broken - total E of bonds
formed; ΔH*f=total Hf of products - total Hf of reactants
⩥ Gibbs free energy: Answer: ΔG=ΔH−TΔS
⩥ Free energy & equilibrium: Answer: ΔG∘=−RTlnK
⩥ Rate law: Answer: Rate=k[A]^m[B]^n
⩥ V initial = Answer: Vmax x ([s])/(Km + [s])
