Kc for reactions
Write the expressions for Kc for the following reactions.a. 2O3(g) --> 3O2(g)
b. Ti(s) + 2Cl2(g) --> TiCl4(l)
c. 2C2H4(g) + 2H2(g) --> 2C2H6(g) + O2(g)
d. C(s) + 2H2(g) --> CH4(g)
e. 4HCl(aq) + O2(g) --> 2H2O(l) + 2Cl2(g)
The Kp for the reaction below is 1.49 × 108 at 100.0 °C: CO (g) + Cl2 (g) ↔ COCl2 (g)
