Question
1)What is the correct expression for the equilibrium constant (Keq) for the reaction between carbon and hydrogen gas to form methane?
C(s)+2H2(g)
2)Consider the reaction:
CO(g)+Cl2(g)COCl2(g)
Find the mistake in the equilibrium expression and fix it.
Keq=[CO][Cl2][COCl2]
Use A for [CO], B for [Cl2], C for [COCl2].
Assign an oxidation state to each element in each reaction and use the change in oxidation state to determine which element is being oxidized and which element is being
C6H12O6(s)+6O2(g)6CO2(g)+6H2O(g)
C2H4(g)+Cl2(g)C2H4Cl2(g)
Express your answers as signed integers. Enter the initial and the final oxidation states separated by a comma
Keq=[CH4][C][H2]2 Keq=[CH4][H2] Keq=[CH4][C][H2] Keq=[CH4][H2]2Explanation / Answer
1)
C (s) + 2H2 (g) <---> CH4 (g)
Keq = concetration of product / concentration of reactant
solid is not considered
Keq = [CH4]/[H2]^2
2)
Correct Kew will be
Keq = [COCl2] / [CO][Cl2]
= C/(AB)
