Question

write the equilibrium expression (K) for each of the following gas-phase reations.
a. N2(g) + O2(g) <-> 2NO
b. N2O4(g) + 2Cl2(g)<->SiCl4 +2H2(g)
c. SiH4(g) +2Cl2(g)<->SiCl4(g) +2H2
d. 2PBr3(g) +3Cl2(g) <->2PCl3(g)+3Br2(g)

Answer 1

k = product of products raised to power their coefficients/product of reactants raised to power their coefficients

Answer 2

Answer 3

I'll do the first one for u: \[k = \frac{ [NO] ^{2} }{ [N _{2}][O _{2}] }\]
