Expert Solution

1) C(s) +H2O(g) ----- CO(g) + H2(g)
1 mole 1 mole
according to equation
1 mole of C= 1 mole of H2
1.16 mole of C = ?
=1.16x1/1=1.16 mole
number of moles of H2= 1.16 moles
Pressure =P= 1.0atm
Temperature = T= 319 K
gas constant = R= 0.0821 L-atm/mol-K
PV=nRT
V= nRT/P = 1.16x0.0821x319/1.0 = 30.38L
Volum of Hydrogen gas = 30.38L=30L

2) CO(g) + 2H2(g) -------- CH3OH(g)
2 mole 1 mole
according to equation
1 mole of CH3OH = 2 mole of H2
0.68 mole of CH3OH =?
= 2x0.68/1=1.36 mole
number of moles of H2= 1.36 moles
Pressure =P= 741mm=741/760=0.975 atm
T=88C=88+273=361K
R=0.0821 L-atm/mol-K
Pv=nRT
V=nRT/P
V= 1.36 x0.0821x361/0.975=41.34L
Volume of H2= 41L

according to equation
1 mole of CH3OH= 1mole of CO
0.68 mole of CH3OH= 0.68 mole of CO
n=0.68 mole
V= 0.68x0.0821x361/0.975= 20.67L
Volume of CO = 20.67L = 21L
