Answer: It will take for the concentration of A to decrease from 0.900 M to 0.210 M is 28.75 s
Explanation:
Zero order reaction : A reaction is said to be of zero order if the rate is independent of the concentration of the reactants, that means the rate is directly proportional to the zeroth power of the concentration of the reactants.
Expression for the zero order kinetics:
![[A]=-kt+[A]_o](https://tex.z-dn.net/?f=%5BA%5D%3D-kt%2B%5BA%5D_o)
where [A] = concentration left after time t = 0.210 M
= initial concentration = 0.900 M
k= rate constant =
t = time for reaction = ?


Thus it will take for the concentration of A to decrease from 0.900 M to 0.210 M is 28.75 s
Hi!
Fuel-cell cars only release water and heat in the atmosphere.
Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think.
Basically, automotive engineers and scientist classified them as zero-emission.
