First to see how Much Norm used, we need to subtract 373 from 500 (500-373) and you get 127. To express this as a fraction you put 127 over 500. then the decimal would be 127 divided into 500. Which is .254 . The answer in fraction form is 127/500 and in decimal is .254
Answer:
1.668 S
Step-by-step explanation:
We are given that
Product
For first order reaction,


Rate constant=k=
Temperature=
We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.


Substitute the values then we get


Hence, it would take 1.668 s for the concentration of A to decrease from 0.790 M to 0.230 M.
The answer is 0.49. But if you meant what is 70% of 70 its 49
