I’m pretty sure true, just not your skull at birth hehe. hope this helps :)
Where are the statements?
Answer:
Air is a mixture of gases
Answer: 7s
Explanation:
The order of the reaction is 2.
Integrated rate law for second order kinetic is determined using the formula
1/[At]=1/[Ao] +kt
But, [Ao] is the initial concentration = 1.50 mol/L
And [At] is the final concentration = 1/3 of initial concentration =1/3×1.5 = 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Using the formula
1/0.5=1/1.5+0.2t
Collecting like terms
1/0.5-1/1.5=0.2t
LCM = 1.5
3-1/1.5=0.2t
2/1.5=0.2t
Multiply both sides by 1/0.2
2/1.5×0.2=t
2/0.3=t
t=6.66s
t=7s
