Question

Half life (t_1/2) and completion time (T) of the zero order reaction are- (K = 0.001 mol/litre/sec and a = 1 M.)

Options

• 500 min, 750 min 

• 500 sec, 750 sec 

• 500 sec, 1000 sec 

• None of these

Answer 1

500 sec, 1000 sec

Explanation:

X = kt so `"t"_(1//2) = "a"/"2k"` and T = `"a"/"k"`

`"t"_(1//2) = 1/(2 xx 0.001) = 500` sec and T = 1000 sec
