What is the change in enthalpy for the single replacement reaction between solid zinc and cs2so4 in solution to produce cesium and znso4? zn + cs2so4 → 2cs + znso4 given: `"cs"_2"so"_4(aq): deltah_f °= –1,400 "kj"` `"znso"_4(aq): deltah_f °= –1,063 "kj"`

The change in enthalpy refers to the amount of heat absorbed or heat evolved in a reaction which is carried out at constant pressure.

The change in enthalpy of a reaction is equal to the sum of formation of products minus sum of formation of reactants. It is denoted by .

The given reaction is:

Substitute the given values (products)  and (reactants) in above formula, we get

=

Thus, change in enthalpy for the single replacement reaction is

b
