Reaction of Iron with Concentrated and dilute hydrochloric acid
No, $\ce{FeCl3}$ is not formed upon reaction with Conc. $\ce{HCl}$. Both dilute and concentrated $\ce{HCl}$ give $\ce{FeCl2}$ as product.

$$\ce{Fe + 2HCl_{dil} -&gt; Fe^2+ +  2Cl^- + H2 ^}$$
$$\ce{Fe + 2HCl_{conc} -&gt; Fe^2+ +  2Cl^- + H2 ^}$$
