Effect of changing temperature

Question 1

What does TupEND stand for?

Answer 1

Temperature up will favour the endothermic reaction

Question 2

What does TrEX stand for?

Answer 2

Temperature reduced will favour exothermic reaction

Question 3

2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
In this reaction, what is the forward reaction?

Answer 3

Exothermic reaction

Question 4

2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
What would happen in temperature increases?

Answer 4

Equilibrium will shift to the left and favour the endothermic reaction
Lead to a decrease in temperature
Yield of products would decrease

Question 5

2SO2(g) + O2(g) ⇋ 2SO3(g)
(ΔH = -ve )
What would happen in temperature decreases?

Answer 5

Equilibrium will shift to the right and favour the exothermic reaction
Lead to an increase in temperature
Yield of products would increase

Question 6

2HI(g) ⇋ H2(g) + I2(g)
(ΔH = + ve)
In this reaction, what is the forward reaction?

Answer 6

Endothermic reaction

Question 7

2HI(g) ⇋ H2(g) + I2(g)
(ΔH = + ve)
What would happen in temperature increases?

Answer 7

Equilibrium will shift to the right and favour the endothermic reaction
Lead to an increase in temperature
Yield of products would increase

Question 8

2HI(g) ⇋ H2(g) + I2(g)
(ΔH = + ve)
What would happen in temperature decreases?

Answer 8

Equilibrium will shift to the left and favour the exothermic reaction
Lead to an decrease in temperature
Yield of products would decrease
