Answer:
to determine the rate of heat loss from that wall by convection = 12780 watts
Explanation:
Answer:
Concentration of A:
Concentration of B:
Concentration of C:
the image shows the graphs of the three concentrations
Explanation:
We have the reaction:
A ------->k1--------->B------------->k2--------->C
Each reaction:
Where Cn is the concentration of each specie (A,B,C)
The mass balance for A:
Where x=CAo and y=CA
The mass balance for B:
The mass balance for C:
The maximum concentration of C is:
and the maximum time is:
