First Order Reactions

Postby AlyssaBei_1F » Mon Mar 04, 2019 12:24 pm

In first order reactions, will it always be a straight line like the graph in lecture from today?

Yes, I believe first order reaction graphs will always be straight lines when they are graphed as ln[R] vs time.

I think the derived ln formula for first order will always be a straight line but I don't think the actual rate law for first order reactions are first order, i'm not totally sure though.

In the slides it says a straight line plot of ln[R] vs time means the reaction is 1st-order.

Yes, It will be a straight line. But I think Lavelle also said if you also see an exponential decrease, that would be [A] graphed and indicate a first order reaction as well

First order reaction graphs are only straight lines when the graph is time vs. ln[A]

I believe it should be a straight line with decreasing slope
