Question

The enthalpy change for the reaction C+029) + CO2(g) is - 94.05 kCal at 25°C. Calculate the enthalpy change at 400°C. Heat capacities of CO2(g), Cs, and O2(e) are 8.96, 2.04 and 7.05 cal/mol-°C respectively. (a)232.2 Kcal/mol (b)-142.8 Kcal/mol (c)-45.3 Kcal/mol (d)-94.098 Kcal/mol​

Answer 1

Answer:

We now introduce two concepts useful in describing heat flow and temperature change. The heat capacity (C) of a body of matter is the quantity of heat (q) it absorbs or releases when it experiences a temperature change (ΔT) of 1 degree Celsius (or equivalently, 1 kelvin)

C=qΔT
