A reaction is second order in A with a rate constant of 0.039/ M s.  The concentration of A was 0.30 M after 23 seconds.  What was the initial concentration of A?  Assume the stoichiometric coefficient for A is 1.

Thank you for the opportunity to help you with your question!

k= 1/t [ 1/a-x -1/a ]
a = initial conc , a-x = conc after 23 sec = 0.3M
0.039 = 1/23 [1/0.3- 1/a]
a = 0.41 M = initial conc of A

Please let me know if you need any clarification. I'm always happy to answer your questions.
