the higher the concentration, the slower the reaction rate
F (higher-faster, lower-slower)
increasing the temperature will make the reaction rate faster because increase potential energy
T
Decreasing particle size will make the surface are larger
F
catalyst decreases the activation energy for a chemical reaction to occur
T
reactant particles must interact with one another before any reaction can occur.
T
a chemical reaction may take place even if it is not properly aligned as long as it will collide
F
molecular collision is more favorable in solids than liquids and gases
F
when chemical equilibrium is reached, the concentrations is constantly changing to maintain the balance.
T
removing reactant will make the equilibrium shift to the product side
F
decreasing temperature will make the equilibrium shift to the reactant side for an exothermic reaction
T
enthalpy of reactants is higher than that of products
EX
enthalpy of reactants is lower than of the product
EN
change is enthalpy is a positive value
EN
change in enthalpy is a negative value
EX
heat is constantly used up for the chemical reaction
EN
heat is release in the environment
