Answer:
molecularity of the rate-determining step
Explanation:
The rate determining step of a sequence of reactions is the slowest step in the sequence of non-elementary reactions.
The molecularity of the slowest step in the reaction mechanism gives us the rate law of reaction.
It is for this cause that the slowest step in the reaction sequence is called ''rate determining step'' since it determines the rate law of reaction.
Emission spectrum
Explanation:
The emission spectrum is the characteristic color bands emitted by element when they become excited.
The spectrum denotes the amount energy that each respective atom absorbs.
Emission spectrum is very unique to every element becomes atoms gives off electromagnetic radiations within a range that typifies them.
The color band indicate the amount of energy emitted in form of electromagnetic radiation.
When electrons in an atom gain energy, the become excited, on falling and losing their energy, they return to their ground state releasing the measure of energy they absorbed in transitioning.

Answer:
The final pressure of the gas sample at constant temperature is 1.20 atm.
Explanation:
Boyle's Law : Volume occupied by fixed amount of gas at a given temperature is inversely proportional to pressure .(moles, temperature are constant )
on transposing ,
PV = constant
............(1)
Initial pressure = P1 = 2.00 atm
Final pressure = P2 = ?
Initial volume = V1 = 300.0 mL
Final volume = V2 = 500.0 mL
Putting values of P1 ,V1, V2 in equation (1) and solving for P2
P2 = 1.20 atm at constant temperature
