Question
Consider the following reaction:
Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g)
Compared to the value for Go (under standard conditions), select every change that 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
reaction "more spontanous" will be if
we increase reactants, therefore they will produce products
---> increase HCl; will make it spontanous
---> increasing Zn metal, will make it spontanous
if we increase pressure of gases, then we increase their concnetration.
---> decreasig H2 pressure, will make it more spontanous
