Considering the reaction, C(s) + O_(2)(g) to CO_(2)(g) + 393.5 kJ the signs of DeltaH, DeltaS and DeltaG respectively are:

Answer»

`+,-,-`
`-,+,-`
`-,-,-`
`-,+,1`

SOLUTION :`DeltaH =-ve` (combustion reaction)
`DELTAS = +ve` (SPONTANEOUS at all temperature)
`DeltaG = -ve` (because reaction is spontaneous)
