A DIAGNOSTIC TEST 39 59. Which data must be collected to calculate the enthalpy of reaction? (A) volume, pressure, initial and final temperature (B) conductivity, concentration, pH (C) initial and final temperature, absorbance, concentration (D) concentration, volume, initial and final temperature 60. How does the temperature change and why does it occur? (A) The temperature increases because potential energy of the chemical bonds is transformed into thermal energy. (B) The temperature increases due to the friction of mixing. (C) The temperature decreases because water formed in the g. ons ner t. reaction has a high specific heat сарacity. (D) The temperature decreases due to decrease in entropy from the formation of a salt.

A DIAGNOSTIC TEST 39 59. Which data must be collected to calculate the enthalpy of reaction? (A) volume, pressure, initial and final temperature (B) conductivity, concentration, pH (C) initial and final temperature, absorbance, concentration (D) concentration, volume, initial and final temperature 60. How does the temperature change and why does it occur? (A) The temperature increases because potential energy of the chemical bonds is transformed into thermal energy. Questions 59-60 refer to the following. The enthalpy of reaction of HCl and NAOH is to be calculated. The solutions are combined in an insulated container that is isolated from the environment. (B) The temperature increases due to the friction of mixing. (C) The temperature decreases because water formed in the reaction has a high specific heat capacity. (D) The temperature decreases due to decrease in entropy from the formation of a salt.
