PORTAGE CHEM 104 MODULE 1 STUDY GUIDE Exam | Questions & 100% Correct Answers (Verified) | Latest Update | Grade A+
Kinetics : the study of rates of reactions and how they are influenced by certain factors Influences Reactions Rates : Concentration, temperature, catalysts, surface area Temperature/Reaction Rate : Increase, higher temperature provides higher kinetic energy Catalyst/Reaction Rate : Increase, without being consumed Surface Area/Reaction Rate : Increase, increased surface area of particles increases reaction rate because solids only react at their surfaces (grinding solid into fine powder) 2 | P a g e Concentration/Reaction Rate : Increase, provides more reacting particles to undergo reaction Reaction Rate : Increase in molar concentration of product per unit of time or the decrease in molar concentration per unit of time Reaction Rate Units : moles per liter per second (mol/L*s) Reaction Rate Equation : Change in concentration/change in time (products=positive, reactants=add negative sign) Average Rate : Determined by using initial and final concentrations and initial and final times so that the result measures
