How is the rate of a chemical reaction related to temperature? A: It is slowed by higher temperature B: It is dependent upon the temperature C: It is Independent of the temperature D: It is unrelated to temperature

it is dependent upon the temperature

Explanation:

This is because if there is no temperature you can't perform chemical reactions

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i think it is true since you can test the answer and can use observations to complete it.
