a) Adding H2(g) to the system will increase the concentration of H2(g) and decrease the concentration of C2H6(g) and C2H4(g).
b) Adding heat to the system will not change the equilibrium concentrations of any of the substances in the system.
c) Adding CuSO4(g) to the system will increase the concentration of Cu2+ (aq) and decrease the concentration of NH3(aq) and Cu(NH3)32+ (aq).
d) Adding Pb (NO3)2(s) to the system will not change the equilibrium concentrations of any of the substances in the system.
e) Adding AgCl(s) to the system will not change the equilibrium concentrations of any of the substances in the system.
2. What is the effect on the equilibrium concentration of each substance in the system (increase, decrease or no change) when the listed reagents are added?
a) H2(g) is added to the system described by:
C2H6(g) = H2(g) + C2H4(g)
b) Heat is added t to the system described by:
CO(g) + ½ O2(g) = CO2(g) + heat
c) CuSO4(g) is added to the system described by:
CU2+ (aq) + 4NH3(aq) = Cu (NH3)32+ (aq)
d) Pb (NO3)2(s) is added to the system described by:
Pb (NO3)4(s) + H+ (aq) = PB2+ (aq) + HSO4-(aq)
e) AgCL(s) is added to the system described by:
Ag+ (ag) + Cl- (ag) = AgCL(s)
5 answers
are you sure this answer is correct?
Apologies for the confusion. Here are the correct answers:
a) Adding H2(g) to the system will shift the equilibrium towards the right, increasing the concentration of C2H4(g) and decreasing the concentration of C2H6(g).
b) Adding heat to the system will shift the equilibrium towards the right, increasing the concentration of CO2(g) and decreasing the concentration of CO(g) and O2(g).
c) Adding CuSO4(g) will not have any effect on the equilibrium concentrations as it is a solid and not a reactant or product in the equation.
d) Adding Pb(NO3)2(s) will not have any effect on the equilibrium concentrations as it is a solid and not a reactant or product in the equation.
e) Adding AgCl(s) will not have any effect on the equilibrium concentrations as it is a solid and not a reactant or product in the equation.
