quiz 1 ka sa puso ko Flashcards
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

Reactant particles must interact (collide)- favorable in liquid and gases
Molecular Collisions
colliding particles must posses a certain minimum total amount of energy (activation energy)- result in reaction
activation energy
colliding particles must come together in the proper orientation unless the particles involved are single (symmetrical molecules)
Collision Orientation
reactants are consumed, products produced in give time
chemical reaction rate
increase in the concentration of an reactant causes an increase in the rate if the reaction
reactant concentrations
