Question

Consider the following reversible reaction.

${\text{C}}{{\text{r}}_2}{\text{O}}_7^{2 - }{\text{(aq)}} + {{\text{H}}_2}{\text{O(l)}} \rightleftharpoons {\text{2CrO}}_4^{2 - }{\text{(aq)}} + {\text{2}}{{\text{H}}^ + }{\text{(aq)}}$

What will happen to the position of equilibrium and the value of ${K_{\text{c}}}$ when more ${{\text{H}}^ + }$ ions are added at constant temperature?
