What statement is true regarding the collision theory? The number of collisions between reactant molecules increases with decrease of temperature. Molecules that are improperly oriented during collision will not react. All collisions of reactant molecules result in product formation. The number of collisions between reactant molecules increases with decrease of reactant concentrations.
Which one of the following conditions must be met for an elementary reaction between two molecules to occur? - Collisions between reactant molecules must have enough energy to form the transition state and convert it into products - The reactant molecules must be in a lower energy state than the products - At least one of the reactant molecules must have a double or triple bond - The molecules must be attracted to one another by ionic forces
Which statement describes a chemical reaction at equilibrium? Reactant molecules and product molecules have the same velocity. Molecules of reactants and products collide with the same frequency. The concentrations of reactants and products are equimolar. Reactants and products are consumed and formed at the same rate.

Dynamic Equilibrium Simulation with Pennies 1 of 11 on Equilibrium is a state where there are no observable changes over time. Equilibrium is achieved when the rate of the forward reaction equals the rate of the reverse reaction. R =P In this activity, we will simulate a reversible reaction where R = P: the reactant molecules (R) are pennies, which react and are transferred from the side to the P side, while the product molecules...
UUUUUUUUU 4. For an endothermic reaction: Is the energy of the products higher or lower than reactants? (circle one) b. Is heat released or absorbed c is the sign for AH positive or negative? S a. Since reactions are favorable when they release energy and form lower energy products, which reaction - (a) or (b) - is favorable? b. What is the sign (+ or -) for the energy (enthalpy) value of a favorable reaction Manager: Check to ensure that...
