Effect of changing temperature Flashcards
(8 cards)
What does TupEND stand for?
Temperature up will favour the endothermic reaction
What does TrEX stand for?
Temperature reduced will favour exothermic reaction
2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
In this reaction, what is the forward reaction?
Exothermic reaction
2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
What would happen in temperature increases?
Equilibrium will shift to the left and favour the endothermic reaction
Lead to a decrease in temperature
Yield of products would decrease
2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
What would happen in temperature decreases?
Equilibrium will shift to the right and favour the exothermic reaction
Lead to an increase in temperature
Yield of products would increase
2HI(g) ⇋ H2(g) + I2(g)
(ΔH = + ve)
In this reaction, what is the forward reaction?
Endothermic reaction
2HI(g) ⇋ H2(g) + I2(g)
(ΔH = + ve)
