What is the heat capacity of crystalline calcium carbide at 49.0°C?
Olenka [21]

Explanation:

Formula to calculate heat capacity is as follows.

               C_{p} = a + bT + cT^{-2}

where, a, b and c are constants.

Their values at 49.0^{o}C are as follows.

     a = 68.62 \times 10^{-3}        

     b = 1.19 \times 10^{-5}

     c = -8.66 \times 10^{10} \times 10^{-8}

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

               C_{p} = a + bT + cT^{-2}

    = 68.62 \times 10^{-3} + 1.19 \times 10^{-5} \times 49.0 + -8.66 \times 10^{10} \times 10^{-8} \times (49.0)^{-2} kJ/mol K    

                             = 14.43 kJ/mol K

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