Answer:
1. 67.2 kJ/mol
Explanation:
Using the derived expression from Arrhenius Equation
Given that:
time = 8.3 days = (8.3 × 24 ) hours = 199.2 hours
time = 10.6 hours
Temperature = 0° C = (0+273 )K = 273 K
Temperature = 30° C = (30+ 273) = 303 K
Rate = 8.314 J / mol
Since
Then we can rewrite the above expression as:
Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
