In the above reaction A is the reactant and B is product
(i) What is the rate constant of the given reaction?
A
0.1 s –1 150 s 50s
B
0.1 M –1 s –1 100 s 100 s
C
0.15 M 
–1 s –1 200 s 150 s
–1 s –1 200 s 150 s
D
0.1moles lit –1 s –1 (ii) What is the half-life period of the given reaction 250 s 
(iii) If the reaction stoichiometry become A ⎯→ 2B at what time in the given reaction [A] and [B] will be equal ? 200 s 
(iii) If the reaction stoichiometry become A ⎯→ 2B at what time in the given reaction [A] and [B] will be equal ? 200 s
Text Solution
Verified by ExpertsThe correct answer is:
0.1
(i)
Sol. 0.1 M –1 s –1
(ii)
Sol. The rate equation is
t = 
= 
= 
or t = 200 s
(iii)
Sol. A ⎯→ 2B
At t = 0 ; 0 0
At t = t ; 0 – x 2x
When = then 0 – x = 2x
or 3x = 0
or x = 
∴ t = 
t = 
= 10 × 
= 
= 
or t = 100 s
