O The Sun is directly over Earth's north end.
O The Northern Hemisphere receives fewer direct rays from the Sun.
O The northern end of Earth's axis is tilted away from the Sun.
The sun is directly over Earth’s north end
Homeostasis, is the natural adaption of the environment
We know that reate constant (-Ea/RT)
K = Ae^(-Ea/RT)
A = frequency factor
Ea = activation energy
R = constant
T = temperature
Let us take two rate constants
<span>K1 = Ae^(Ea1/RT) </span>
K2 = Ae^-(Ea2/RT)
K2 = K1/H
<span>H = e^ (Ea2/RT - Ea1/RT)</span>
1.386 = 1/RT (Ea2 – HG Kj/mol)
<span>Substituting everything to the equation, we get 3.43 kJ/mol</span>
