Question 1

Arrhenius equation

Answer 1

K=Ae^(-Ea/RT)K is rate constantA is frequency factorEa is activation energy (in J/mol)R = 8.314J/mol • K

Question 2

ln k = -Ea/R • (1/T) + ln A

Answer 2

Simplified Arrhenius equation

Question 3

42 He

Answer 3

Atomic notation4 is mass number(2 neutrons and 2 protons)2 is proton number

Question 4

Nuclear strong force

Answer 4

Short range and strongly attractive between n-n, p-n and p-p

Question 5

Alpha Decay(α)

Answer 5

Emits a Helium NucleiTravel up to 1” in air

Question 6

Beta Decay(β)

Answer 6

Emits a high speed electronTravel several feet in air

Question 7

Gamma radiation(γ)

Answer 7

Electromagnetic energyTravel 10-100 ft in air

Question 8

Electron capture (radioactive Decay)

Answer 8

Proton grabbed electron to become a neutronPositron - electron mass but positive charge

Question 9

Neutron activation

Answer 9

Nucleus picks up a neutron, becoming unstable, thus emitting an electron, picking up another neutron

Question 10

Chain reactions for nuclear fission

Answer 10

Critical mass is required to sustain this reaction (cantaloupe size for 235-U)

Question 11

Radioactive decay is independent

Answer 11

Of physical state, temperature
