The answer to the question which of the following statements is TRUE is
c. Rate constants are temperature dependent.
Explanation:
The rate constant can be derived from the following Arrhenius equation thus
k =![Ae^{-\frac{E_{a} }{RT} }](/tpl/images/0508/2639/52dc5.png)
Where A = Arrhenius constant
R = Universal gas constant
T= Absolute temperature
Eₐ = Activation energy of the reaction
The above equation makes it clear that the rate of a reaction is mainly impacted by the temperature of the reaction.
The rate constant therefore is not actually a constant as it is only valid for a specified temperature

Explanation:
The green alternative
Unlike fossil fuels, green energy made from wind and solar power is sustainable, because its generated by resources that won't run out.
