2. Which of the following methods will usually cause a reaction to speed up? A. Combining the reactants at a lower temperature. O B. Reducing the concentration of reactants. C. Grinding one of the reactants into a powder. O D Removing the catalyst.
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. The molecules will not have the correct orientation for the collision to be effective. They will fuse, forming one atom, which will then rearrange its protons to create new products. They will simply move away from each other again, unchanged.
(i) energy does not change,(ii) always absorbed energy,(iii) energy is always released,(iv) reactants may be formed.Which statement is true about the decomposition of an activated complex? A. (iii) and (iv)B. (i), (iii) and (iv)C. (ii) and (iii)D. (i), (ii) and (iv)E. (i) and (ii)
If a chemical reaction is going to move forward, what part of the reaction must collide? A. reactants and products B. reactants with activated complex C. products only D. reactants only
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. OThis point is the temporary unstable arrangement of atoms where old bonds are broken and new bonds are forming.
Why does the rate of most reactions decrease over time? A. A decrease in reactant concentration reduces the frequency of successful collisions. B. A decrease in temperature reduces the average kinetic energy of the particles. C. An increase in product concentration interferes with the effectiveness of the catalyst. D. An increase in pressure of the system reduces the movement and energy of particles.
