CHEMICALKINETIC-QN10
Basing on the temperature, identify exothermic and endothermic reaction.
i) H2+ N2⇌ NH3 Δ
H= 150 kg/mole
ii) CaCO3⇌ CaO+CO2 ΔH = 1100kg/mole
iii) H2 + I2⇌
CI Δ H = 450kg/mole
iv) C + H2 CH3 Δ H = 20kg/mole
v) SO2 + O2 ⇌ SO3 Δ
H = -200kg/mole
-
Soln:
i) Exothermic reaction
ii) Endothermic reaction
iii) Endothermic reaction
iv) Endothermic reaction
v) Exothermic reaction
