NEET Chemistry Chemical Kinetics Questions Solved


Half-life is independent of concentration of reactant. After 10 minutes volume of N2 gas is 10L and after complete reaction it is 50 L. Hence rate constant is

1. (2.303/10)log5 min-1

2. (2.303/10) log 1.25 min-1

3. (2.303/10) log 2 min-1

4. (2.303/10) log 4 min-1

(2) 

At t=0,             a            O         O

At t= 10,        (a-x)         x         x

At t= ,          0            a         a

At t = 10 min, x - 10 L 

At t = , a = 50 L 

K = (2.303/10) log (50/50-10)

K = (2.303/10)log1.25
