State whether the following is true or false.
Kirchhoff's relation corrects a heat of reaction from one temperature to another using heat capacities.

  • A.True
  • B.False
  • C.True only at large scales
  • D.False only at small scales

Answer: A

The change in the heat of reaction with temperature is the difference between the product and reactant heat capacities. Integrating that difference is the standard way of moving a tabulated value to the reaction temperature.
