Answer:
-14.60 kJ/mol
Explanation:
Equation for the reaction
A --------------> 2B + 3C
The ICE Table is shown as:
A --------------> 2B + 3C
Initial 9.13 0 0
Change - x + 2x + 3x
Equilibrium 9.13-x 2x 3x
(9.13-x)+2x+3x = 16.89
9..13 - x +5x = 16.89
9.13+4x = 16.89
4x = 16.89-9.13
4x = 7.76
x =
x = 1.94
Equilibrium pressures are as follows:
A = 9.13 -x
= 9.13 - 1.94
= 7.19 atm
B = 2x
= 2 (1.94)
= 3.88 atm
C = 3x
= 3(1.94)
= 5.82 atm
