Answer to Question #55574 in General Chemistry for Nickolai

Question #55574
The rate constant for this zero-order reaction is 0.0380 M·s–1 at 300 °C.
A --> Products
How long (in seconds) would it take for the concentration of A to decrease from 0.920 M to 0.340 M?
Expert's answer
Zero order reaction equation:
[A] = [A]0 – kt;
[A]0 – [A] = kt;
t = ([A]0 – [A])/k = (0.920 M – 0.340 M)/(0.0380 M s-1) = 15.3 s
Answer: 15.3 s
