What is the equation for the second step?
A
.
6
Q
What is the forward and backwards reaction?
A
.
7
Q
why is there no need for very high pressure for this reaction?
A
As the equilibrium is already positioned far to the right due to the mol of stage two being 2 it is enough to push through the converter.
8
Q
what are the conditions chosen for the reversible reaction?
A
.
9
Q
Why is the temperature of 450 degrees chosen?
A
Compromise temperature good yield and rate of reaction.
high enough for the enzyme to work as it only works above 380 degrees.
