Explanation:
(a) A number which is dimensionless and provides us an estimate of the degree of conversion which can be achieved in CSTR, that is, continuous stirred tank reactor is known as Damkohler number.
This number is denoted as Da.
Mathematically, Da = 
Da = 
Now, for first order system, Da =
= 
= Tk
where, rA = rate of reaction
V = volume of reactor
= molar flow rate of component A
k = rate constant
= initial concentration of A
v = volumetric flow rate of A
T = residence time
(b) Since, from a given Damkohler number we can figure out the possible conversion of CSTR, that is, continuous stirred tank reactor.
So, if we have a low Damkohler number then the system will give us a less conversion formula. As the conversion is as follows.
X = 
Hence, we can conclude that 
will give less than 10% conversion as calculated by using above formula.
Explanation:
The given data is as follows.
, 
= 2257 kJ/kg, 
= ?
For water, 
= 4.184 
Formula to calculate heat of vaporization is as follows.
= 
Hence, putting the values into the above formula as follows.
=
= 
= 2257 kJ/kg - 376.56 kJ/kg
= 1880.44 kJ/kg
Thus, we can conclude that enthalpy of liquid water at 
is 1880.44 kJ/kg.
Answer:
i would say false.
Explanation:
some discoveries are made as people continue exploring the world...........they are just prooved in the laboratory, while there are other which are still made in the lab and are also examined there.

That is the only one I know :)
