At 400k, the equilibrium constant for the reaction Br2(g) + Cl2 (g) is Kp= 7.0 p. A closed vessel at 400k is charged with 1 atm of Br2(g), 1 atm of Cl2 (g), and 2.00 atm of BrCl(g). Use Q to determine which of the statements is true below.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
