Sapling #2 (week 9/10)
How would I find the rate of A? In the feedback, it was mentioned that I needed to find A before I could find out the rate of B. Can someone help me with this?

Re: Sapling #2 (week 9/10)
Hi! I can help with this one. This is the advice the problem gives, so let's follow it step by step.
"First, find the rate of change for A.
rateA=delta[A]/delta t
where delta[A] is the change in concentration of A, during the time period delta t."
We can see from the table that delta[A] is equal to 0.710 M- 0.140 M, or 0.57 M.
We can also see from the table that delta t is 222 seconds.
We can then dive to find the rateA, so we do 0.57 M/222 s, and we get 0.00256756756 M/s.
The problem also tells us:
"The product, B, appears twice as fast as A disappears."
So we can multiply our rateA by 2 to get the rateB.
Hope this helps!
