Calculate the entropy change in surround...

Calculate the entropy change in surroundings when 1.00 mole of `H_(2)O_((l))` is formed under standard conditions `Delta_(f)H^(theta)=-286 kJmol^(-1)`.

Text Solution

Verified by Experts

Formula `triangleS =(triangle_(r)H^@)/(T)=(-286)/(273)=-"1.0476 KJ/mole. K"`
`triangleS_("surrounding")=" 1.0476 Kl/mole. k"`
