What is the heat capacity of crystalline calcium carbide at 49.0°c?

Explanation:

Formula to calculate heat capacity is as follows.

                = a + bT +

where, a, b and c are constants.

Their values at are as follows.

     a =        

     b =

     c =

Hence, putting the given values into the above formula as follows.

                = a + bT +

    = kJ/mol K    

                             = 14.43 kJ/mol K

Thus, we can conclude that the heat capacity of crystalline calcium carbide at 49.0 is 14.43 kJ/mol K.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
