Question

The reaction 2X B is a zeroth orer reaction. If the initial concentration of X is 0.2 M, the half-life is 6 h. When the initial concentration of X is 0.5 M, the time required to reach its final concentration of 0.2 M will be :

Accepted Answer

Correct answer: C. (c) For the reaction 2X B, follow zeroth order Rate equation is Kt= (A )_0- (A ) For the half-life; t=t_ 12 and (A )=0.1 K_ 12=0.2-0.1 0.2-0.16= 0.16Mhr^-1 ∴ Time required to reach from 0.5 M to 0.2 M Kt= (A )_0- (A ) 0.16 t=(0.5-0.2) ;t=18hour

$The reaction 2 X \to B is a zeroth orer reaction. If the initial concentration of X is 0.2 M, the half-life is 6 h. When the initial concentration of X is 0.5 M, the time required to reach its final concentration of 0.2 M will be :$
