16.4 Exercise 14

Avg difficulty 2.5

Calculate the equilibrium constant at the temperature given.

(a) O2(g)+2F2(g)⟶2F2O(g)(T=100°C)\text{O}_{2} \left(g\right) + \text{2F}_{2} \left(g\right) \rightarrow \text{2F}_{2} \text{O} \left(g\right) \left(\text{T} = 100 °\text{C}\right)

(b) I2(s)+Br2(l)⟶2IBr(g)(T=0.0°C)\text{I}_{2} \left(s\right) + \text{Br}_{2} \left(l\right) \rightarrow \text{2IBr} \left(g\right) \left(\text{T} = 0.0 °\text{C}\right)

(c) 2LiOH(s)+CO2(g)⟶Li2CO3(s)+H2O(g)(T=575°C)\text{2LiOH} \left(s\right) + \text{CO}_{2} \left(g\right) \rightarrow \text{Li}_{2} \text{CO}_{3} \left(s\right) + \text{H}_{2} \text{O} \left(g\right) \left(\text{T} = 575 °\text{C}\right)

(d) N2O3(g)⟶NO(g)+NO2(g)(T=−10.0°C)\text{N}_{2} \text{O}_{3} \left(g\right) \rightarrow \text{NO} \left(g\right) + \text{NO}_{2} \left(g\right) \left(\text{T} = −10.0 °\text{C}\right)

(e) SnCl4(l)⟶SnCl4(g)(T=200°C)\text{SnCl}_{4} \left(l\right) \rightarrow \text{SnCl}_{4} \left(g\right) \left(\text{T} = 200 °\text{C}\right)
