Question

Sketch the energy diagram representing
the reaction MgCl2(s)¡Mg(s) +
Cl2(g) knowing that the internal energy
for a mixture of Mg(s) and Cl2(g) is
larger than that of MgCl2(s).

H2(g), O2(g)
Initial –
state
AE <0
Final
state
H2O(1)
Einitial greater than Efinali
therefore, energy is released
from system to surroundings
during reaction and AE <0.
A Figure 5.6 Energy diagram for the
reaction 2 H2(g) + 02(g) → 2 H20(1).
Internal energy, E-
