Easy
An isothermal liquid phase zero order reaction A→B (k=0.5 mol/m³-s) is carried out in a batch reactor. The initial concentration of A is 2 mol/m³. At 3 seconds from the start of the reaction, the concentration of A in mol/m³ is _____
0.5 mol/m³(± 0.02 accepted)
Explanation
For a zero order reaction in a batch reactor, CA=CA0−kt=2−0.5×3=2−1.5=0.5 mol/m³.
