The physical properties because when it is physically changed you can identify the change. In chemical changes it sometimes deals with chemicals and stuff that include the breaking of bonds with another element.
If you're asking about the greatest amplitude of visible sunlight, then red light waves.
However if you're talking about the colors just in general, then radio waves.
Answer:
Activation energy for the reaction is 39029J/mol
Explanation:
Arrhenius equation is an useful equation that relates rate of reaction at two different temperatures as follows:
<em>Where K₁ and K₂ are rate of reaction, Ea is activation energy and R is gas constant (8.314J/molK</em>
If the reaction at 400K is 50 times more faster than at 300K:
K₂/K₁ = 50 where T₂ = 400K and T₁ = 300K:
Ea = 39029 J/mol
<h3>Activation energy for the reaction is 39029J/mol</h3>
