________ is used in the neck of the flask as it allows the gas to escape.
photochemical reactions
The rate of some ________, which occur in presence of light, increases with increase in the intensity of suitable light used.
data logger
The ________ does not make the mass balance any more accurate.
orientation factor
The ________ also affect the interaction between reactants and catalysts.
correct orientation
The reaction between the reactants occurs only when they collide in ________ in space.
solid state
Usually solvents help in breaking the cohesive forces between ions or molecules in the ________.
volume of a gas
The ________ is measured using a gas syringe, or an upside down burette or measuring cylinder.
measuring the amount of light that passes through a reaction mixture (as a precipitate forms) over time
this can be done by inspection or using a light sensor and data logger
catalyst
A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.
concentration
In science, the amount of a substance, such as a salt, that is in a certain amount of tissue or liquid, such as blood.
reacting particles
Reacting particles can form products when they collide with one another provided those collisions have enough kinetic energy and the correct orientation.
particles
a minute portion of matter.
product
an article or substance that is manufactured or refined for sale
bonds
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
collide
hit by accident when moving.
stereochemistry
the study of the three‐dimensional structure of molecules
