Answer:
6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.
Explanation:
![Rate = k[AB]^2](https://tex.z-dn.net/?f=Rate%20%3D%20k%5BAB%5D%5E2)
The order of the reaction is 2.
Integrated rate law for second order kinetic is:
Where,
is the initial concentration = 1.50 mol/L
is the final concentration = 1/3 of initial concentration =
= 0.5 mol/L
Rate constant, k = 0.2 L/mol*s
Applying in the above equation as:-


<u>6.66 s will it take for [AB] to reach 1/3 of its initial concentration 1.50 mol/L.</u>
Answer: The specific heat capacity of the unknown metal given is
.
Explanation:
Given: Mass = 225 g
Change in temperature = 
Heat energy = 1363 J
The formula used to calculate specific heat is as follows.

where,
q = heat energy
m = mass of substance
C = specific heat
= change in temperature
Substitute the values into above formula as follows.

Thus, we can conclude that the specific heat capacity of the unknown metal given is
.
