Chemical reactions occur when molecules or atoms collide, the bonds between atoms are broken, and new bonds are formed. Breaking the bonds of the reactants requires energy; bond formation releases energy Which of the following statements regarding energy changes during a reaction are true? The energy of a collision between atoms or molecules must be greater than or equal to the activation energy (Ea) for bonds to be broken. When the...

Which one of the following statements is true? O A catalyst alters the equilibrium constant of a reaction and is neither a product nor a reactant in the overall equation. In order for a reaction to occur, product and reactant molecules must collide with each other. The transition state is a short-lived, high energy state, intermediate between products and reactants. In reactions that are first order in one reactant and first order in another, the slow step always involves a...

Question 1 (1 point) According to the molecular collision theory, which of the following is needed for a reaction to occur? Kinetic energy only High temperature and proper orientation O Proper orientation and kinetic energy High concentration and high temperature Question 2 (1 point) True or False. Equilibrium exists when the forward and reverse rates are different in a reversible chemical change True False

Chemical reactions involve the making and breaking of chemical
bonds. Since different types of bonds have different bond
strengths, the energy of the reacting system changes as the
reaction progresses. A graph that shows the change in energy as a
function of the progress of the reaction is known as a reaction
profile.
According to the theories of chemical reactions, when molecules
collide in the correct orientation with a sufficient amount of
energy, an activated complex or transition state is...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
