Compared to the value for Go (under standard conditions), which option/options will make the reaction MORE spontaneous?
Increasing the concentration of HCl
Increasing the concentration of ZnCl2
Increasing the pressure of H2
Decreasing the pressure of H2
Increasing the amount of zinc metal
Increasing the concentration of HCl
Increasing the concentration of ZnCl2
Increasing the pressure of H2
Decreasing the pressure of H2
Increasing the amount of zinc metal
Explanation / Answer
Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g)
Dg0 rxn is -ve. so that it is spontaneous.
Increasing the concentration of HCl
Increasing the amount of zinc metal
