What is the activated Complex in a heating curve ? O The amount of energy needed to raise the temperature of 1 gram of any substance 1 degree Celsius. O the point phase diagram where a substance will exists as a solid, liquid, and gas at the same time. O Makes the reaction happen faster. This point is the temporary unstable arrangement of atoms where old bonds are broken and new bonds are forming.

When two molecules collide at room temperature, which of the following is not one of the possible results? Question 22 options: They will form an activated complex, which will then lead to products.
