chemistry 12

posted by .

Im doing a worksheet and i had to draw PE diagram which had the Ea(activation energy)at 80kJ and the enthalpy change is -40kJ.
*All the reactants and products are gases
Then it asks to describe what would happen to the diagram if the temperature dropped 25 degrees Celsius. Im not sure what the next thing i need to do is exactly and if i need to do other calculations.
If you could help me understand what its asking me to do
