For my homework I got this problem that my professor never went over in class how to do it and I don't know how to interpret it.

A chemist runs a second order reaction of A->B starting at 10mili moles/L concentration of A (and no B). After one hour the concentration of the product has reached 6mili moles/L. Plot the concentration of B over the time until it reaches 9mili moles.

Do I start with this formula:

1/[A7]=kt+(1/A0)

How would I solve this problem and how would I put it in excel?

If you could help me out, I would really appreciate it.
