Chemistry - Thermochemistry Question with Solution | TestHub

Bomb calorimeter is commonly used to find the heat of combustion of organic substances which consists of a sealed combustion chamber, called a bomb. If a process is run in a sealed container then no expansion or compression is allowed, so$\mathrm{w}=\mathrm{ }0$and$\mathrm{\Delta }\mathrm{U}=\mathrm{q}=-\mathrm{ve}$(exothermic reaction) .

$\mathrm{\Delta }\mathrm{U}\mathrm{ }<0,\mathrm{w}=\mathrm{ }0$
