Answer:
The correct answer is "430 kJ/kg". A further explanation is given below.
Explanation:
The given values are:
T₁ = 400 k
T₂ = 800 k
The average temperature will be:
=
=
=
From table,
At 600 k the will be = 1.075
Now,
⇒ The specific enthalpy =
⇒
⇒
Answer: a) is the limiting reagent
b) 3.59 g
c) 11.6g
Explanation:
To calculate the moles :
According to stoichiometry :
a) 9 moles of require= 4 moles of
Thus 0.15 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
b) As 9 moles of give = 8 moles of
Thus 0.15 moles of give =
of
Mass of
c) As 9 moles of give = 3 moles of
Thus 0.15 moles of give =
of
Mass of
