Which would slow down a reaction that is occurring in a solution at 25 degrees Celcius? Question 11 options:

increase the air pressure above the solution

add a catalyst

put the solution over ice

add 10mL of water at 30 degree Celcius

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.
