Assign the sign of work done (based on SI convention) in the following chemical change taking place against external atmospheric pressure.
(i) `N_(2)O_(3)(g)rarr NO(g)+NO_(2)(g)`
(ii) `MgCO_(3)(g)rarr MgO(s)+CO_(2)(g)`
(iii) `C_(6)H_(6)(l)+(15)/(2)O_(2)(g)rarr 6CO_(2)(g)+3H_(2)O(l)`
(iv) `3H_(2)(g)+N_(2)(g)rarr 2NH_(3)(g)`
(v) `N_(2)O_(4)(g)rarr 2NO_(2)(g)`

Text Solution

AI Generated Solution

To determine the sign of work done for each of the given chemical reactions based on the SI convention, we will calculate the change in the number of moles of gaseous products (Δn_g) and apply the formula for work done (W = -PΔV). ### Step-by-Step Solution: 1. **Understanding Work Done**: - The work done (W) is calculated using the formula: \[ W = -P \Delta V ...
