What is the mathematical equation used when solving calorimetry problems? What does each variable in the equation represent?

Answer : The mathematical equation used when solving calorimetry problems is:

Explanation :

Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.

Formula used :

where,

c = specific heat capacity  of calorimeter

m = mass of a substance

q = heat required

= change in temperature of substance

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
