Question

Half life $\left(t_{1/2}\right)$ and completion time $(T)$ of the zero order reaction are-
$(K=0.001mol/$ litre $/sec$ and $a=1M.)$

• A. 500 min , 750 min
• B. 500 sec , 750 sec
• C. 500 sec , 1000 sec
• D. None of these

Answer 1

Answer: (C)

$X=kt$ so $t_{1/2}=\frac{a}{2k}$ and $T=\frac{a}{k}$

$t_{1/2}=\frac{1}{2\times 0.001}=500$ sec and $T=1000$ sec
