Abatch chemical reactor achieves a reduction in concentration of compound a from 90 mg/l to 10 mg/l in one hour. if the reaction is known to follow zero order kinetics, determine the value of the rate constant in (mg/l. hr) unit.

value of the rate constant is 80 mg/L-hr

Explanation:

given data

concentration of compound Cao = 90 mg/l

Ca = 10 mg/L

time = 1 hour

solution

we use here  zero order reaction rate flow

-rA = K Ca

= K

-d Ca = k dt

now we will integrate it on the both side by Cao to ca we get

solve it we get

cao - Ca = K t

put here value  and we get K

90 - 10 = K 1

K = 80 mg/L-hr

so value of the rate constant is 80 mg/L-hr

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
