Answer : The amount of heat evolved by a reaction is, 4.81 kJ
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water = 254 g
= change in temperature =
Now put all the given values in the above formula, we get:
Therefore, the amount of heat evolved by a reaction is, 4.81 kJ
