Solution

$_{26}^{56} F e \to 2_{13}^{28} A l$
$M_{1} = 55.93494 u$ is atomic mass of $F e$ .
$M_{2} = 27.98191 u$ is atomic mass of $A l$ .

$Q$ value is $(M_{1} - 2 M_{2}) \times 931.5 M e V$
$(55.93 - 2 \times 27.98) \times 931.5$
$\Rightarrow - 26.902 M e V$

$Q$ is negative. Hence fission is not possible.
