10:57 ขึ Your answer is incorrect. Question 4 Incorrect Mark 0.00 out of 1.00 P Flag question Two solutions, one with a mass of 16.66 g, initially at 20.86 °C, and one with a mass of 66.82 g, initially at 26.79 °C were combined which resulted in a reaction taking place. The solution after mixing and reacting had a temperature of 50.04 °C. Calculate the heat associated with the reaction, assuming all solutions have a heat capacity of 4.341 JK-1...
Question 6 Not answered Marked out of 1.00 If the above reaction could be done at 3399 K, what would be your estimate for AGº (in kJ) at this elevated temperature? Use AG° =AH° -TAS® and assume AH° and 4Sº are independent of temperature. P Flag question (Theº is included because it is still for standard conditions, that is, 1 atm for gases and 1 molar for concentrations.) Answer: What is Agrº (in kJ) at 2268 K for the following...
