I found the order (first order) but I don't see how I can calculate the value of the rate constant without a rate! I only have time and M(right column). How do I calculate it? I know k= (A) and I haven't a clue on how to predict the concentration at 280 s. Will someone explain to me please?
The data below show the concentration of versus time for the following reaction:
150 0 .310
Determine the value of the rate constant: ???
Predict the concentration of at 280: ?????
