Explain how/why decreasing temperature affects rate in terms of collision theory.

2. Explain how temperature increases the rate of a reaction. Use the collisiontheory in your answer.

Which of the following statements is true, according to the collision theory?   Question 15 options:   All collisions result in reactions.   Entities must collide to react.   Entities that collide but are incorrectly oriented will form a different product.   All entities in a collision have the same quantity of kinetic energy.

Consider the following general reaction for which gases A and B are mixed.in a constant volume container: A(g) + B(g) -> C(g) + D(g) According to collision theory, what happens to the rate of the reaction under the following changes: (consider each change separately) increase the temperature decrease the temperature increase the volume there is no change to the reaction rate A. decrease the volume the reaction rate increases В. decrease the pressure the reaction rate decreases C. collision theory does not allow you to predict the change in reaction rate increase the pressure D. decrease the concentration increase the concentration

Why does increasing temperature increase a reaction rate?

use the collision theory to explain why concentration has this effect on reaction rates

How Concentration and temperature also affect reaction rate ?

At chemical equilibrium, what is true about the forward rate and reverse rate? The forward rate is greater than the reverse rate The forward rate is less than the reverse rate The forward rate is changing faster than the reverse rate The forward rate is the same as the reverse rate

2. A catalyst is a substance that increases the rate of a chemical reaction but is not consumed by the reaction. A catalyst works by lowering the activation energy for a reaction, making it easier for reactants to form products. What effect, if any, would a catalyst have on a system already at equilibrium? Briefly explain.

Restate the collision theory in your own words. Apply the concepts of collision theory to determine if the rate of reaction between zinc metal and hydrochloric acid will either increase or decrease under the following conditions: Decreasing the temperature of the hydrochloric acid Increasing the concentration of the hydrochloric acid Adding a catalyst to the reaction
