Asked by chantel
a concentration-time study of the gas phase reaction a 2A3 -> 3A2 produced the data in the table below.
time [A3] (M) [A2] (M)
0 4.00 *10^-4 0
10 2.00 *10^-4 3.00 *10^-4
20 1.00 *10^-4 4.50 *10^-4
10 5.00 *10^-5 ?
A) What is the concentration of A2 in the time interval 20-30 seconds?
I got 7.50 x 10^-6
B) What is the concentration of A2 after 30 seconds?
I'm confused on how to do both problems please help
