Vapours of Iodine are in violet colour

Q. Which of the following reactions can be followed by its colour change?

$S O_{2} (g) + 1/2 O_{2} (g) ⇌ S O_{3} (g)$

$N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$

$2 H I (g) ⇌ H_{2} (g) + I_{2} (g)$

$C$ (graphite) $+ C O_{2} (g) ⇌ 2 CO (g)$

Q. Which of the following reactions can be followed by its colour change?

SO2​(g)+1/2O2​(g)⇌SO3​(g)

N2​(g)+3H2​(g)⇌2NH3​(g)

2HI(g)⇌H2​(g)+I2​(g)

C (graphite) +CO2​(g)⇌2CO(g)
