Question 62

Multiple Choice

Express the equilibrium constant for the following reaction:
\quad\quad 2Na(s) + 2H2O(l) ? 2NaOH(aq) + H2(g)


A)
Kc = [NaOH]2[H2][Na]2[H2O]2\frac { [ \mathrm { NaOH } ] ^ { 2 } \left[ \mathrm { H } _ { 2 } \right] } { [ \mathrm { Na } ] ^ { 2 } \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] ^ { 2 } }
B)
Kc = [H2][NaOH]-2
C)
Kc = [Na]2[H2O]2[NaOH]2[H2]\frac { [ \mathrm { Na } ] ^ { 2 } \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] ^ { 2 } } { [ \mathrm { NaOH } ] ^ { 2 } \left[ \mathrm { H } _ { 2 } \right] }
D) Kc = [H2][NaOH]2
E)
Kc = [NaOH]1/2[H2][Na]1/2[H2O]1/2\frac { [ \mathrm { NaOH } ] ^ { 1 / 2 } \left[ \mathrm { H } _ { 2 } \right] } { [ \mathrm { Na } ] ^ { 1 / 2 } \left[ \mathrm { H } _ { 2 } \mathrm { O } \right] ^ { 1 / 2 } }
