Question: How does temperature affect the rate of a chemical reaction? 1. Observe: Select the ANIMATION tab. View the animation with No catalyst selected. What do you see? the higher the temperature, the faster the chemical reaction. When two reactant molecules meet, they form a temporary structure called an activated complex. The activated complex breaks up into the product molecules. 2. Observe: Return to the CONTROLS pane. Set the Temperature to 0 °C and the Simulation speed to its max...

Kelvin A temperature scale based on absolute zero Absolute zero The coldest possible temperature, 0 Kelvin, that can be reached. It is the hypothetical temperature at which all molecular motion stops. controlled experiment An experiment in which only one variable is changed while keeping all other variables constant. Ex: If you were investigating the effect of temperature on the rate of diffusion, you would experiment with different temperatures, but leave the particle mass, ...

rate of chemical reaction A rate is a measure of how much something changes within a specified amount of time. In chemistry, the rate of a chemical reaction, or the reaction rate, is usually expressed as the change in the amount of reactant or product per unit time. Collision Theory A model called collision theory is used to relate the properties of particles to the rates of chemical reactions. According to collision theory, atoms, ions, and molecules can react to form products when t...

Assignment_II.3_Collision_Theory_GIZMO Date: Student Exploration: Collision Theory Vocabulary: activated complex, catalyst, chemical reaction, concentration, enzyme, half-life, molecule, product, reactant, surface area Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Suppose you added a spoonful of sugar to hot water and another to ice-cold water. Which type of water will cause the sugar to dissolve more quickly? Hot water 2. Suppose you held a lighted mat...

The orientation of the molecules in a collision must allow for contact between: the atoms that will be bonded to one another in the product Regarding collision theory for bimolecular and higher order reactions,which of the following are FALSE? (select all that apply) An increase in concentration leads to fewer collisions between reacting molecules. Collisions with the correct orientation will always result in a reaction. Reactions can occur without properly oriented collisions. ...
