At 298 k, the equilibrium concentration of o2 is 1.6 x 10-2 m, and the equilibrium concentration of o3 is 2.86 x 10-28 m. what is the equilibrium constant of the reaction at this temperature?
a. 2.0*10∧-50
b. 2.0*10∧50
c. 1.8*10∧-26
d. 1.8*10∧26

On edg the correct answer is A. I just took the unit test review and got it wrong.

Answer : The correct option is, (A)

Solution : Given,

Concentration of =

Concentration of =

The given balanced equilibrium reaction is,

The expression for equilibrium constant will be,

Now put all the given values in this formula, we get

Therefore, the value of equilibrium constant is,

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 need mutiple choices
