Exothermic
Forward reaction favoured by low temp
More yield ICl3
Yelllo solid produced

i wrote this very answer but still...they said that W exists as a native metal then later said it can be reduced by Carbon...i think someone wrote W by mistake instead of Y

Yeah, so W can exist as native element and be reduced by carbon at the same time cuz it is lower than carbon in the reactivity series (any thing below carbon can be reduced by it)

I put the native element the last. The one that reacted with cold water the highest. What did you put?

What was that reversible reaction of Copper chloride of blue and pink in paper 11? I know it turns back to pink, but does temperature increase or decrease in the reverse reaction?
