Question
Consider the following thermochemical equation: From this equation, we may conclude that 66.2 kJ is the quantity of heat that is lost to the surroundings when 1 mol of O_2 is consumed at constant pressure. lost from the surroundings when 2 mol of NO_2 is formed at constant pressure. gained from the surroundings when 1 mol of NO_2 is formed at constant pressure. gained from the surroundings when 2 mol of NO_2 is formed at constant pressure. lost to the surroundings when 1 mol of NO2 is formed at constant pressure.Explanation / Answer
B is true, when 2 mol of NO2, the reaction requires energy from the surrodings
all other are wrong
NOTE: D is pretty similar to B, but the analysis must inlude the "gained" to surroundings, when in reality surroundings must give energy to the system
