Cr2O3+ 2Al -----------> 2Cr+ Al2O3
Cr2O3--------2Cr.
( oxidation no. of cr +3 to +1 means hain of electron so it act as oxidizing agent)
similarly,
2Al------> Al2O3
( oxidation no. of Al +1 to +3 means loss of electron so it act as reducing agent)

Answer:
204.8 K
Explanation:
We use the ideal gas equation:
PV = nRT
where R is the gas constant (0.082 L.atm/K.mol).
We have the following data:
n= 4 moles
P = 5.6 atm
V = 12 L
So, we introduce the data in the ideal gas equation to calculate the temperature (T):
T = PV/nR = (5.6 atm x 12 L)/(4 mol x 0.082 L.atm/K.mol) = 204.8 K ≅ -68 °C
