Riddles

100

I shift with concentration, pressure, and heat,
Favoring products or reactants, I make equilibrium neat. Who am I?

Le Châtelier’s Principle

200

I set the minimum bar for a reaction to start,
Without me, molecules stay far apart.
Catalysts lower me, but I never go below zero.
What am I?

Activation Energy

300

I tell gases how fast they move in a spread,
My bell-shaped curve shows who’s slow and who’s sped.
What distribution am I?

Maxwell–Boltzmann distribution

Thermodynamics

100

This state function tells you if a process is spontaneous at constant T and P.

Gibbs free energy

200

This law says entropy of the universe always increases.

Second Law of Thermodynamics

300

This thermodynamic quantity is defined as the heat exchanged at constant pressure

Enthalpy

Quantum

100

This Greek letter represents the wavefunction.

ψ (psi)

200

This model incorrectly assumed electrons travel in fixed circular orbits.

Bohr model

300

Four cases in which classical mechanics fails to accurately describe microscopic systems

1. Black body

2. Heat Capacity

3.Photoelectric

4.Emission spectra

Kinetics

100

This is the name of the minimum energy required for a reaction to occur

Activation energy

200

A straight line in a plot of ln[A] vs. time tells you this about the reaction order

first order

300

This equation shows how reaction rate depends exponentially on temperature and activation energy.

Arrhenius equation

Lab

100

This compound in glow sticks reacts with hydrogen peroxide to create a high-energy intermediate that powers the light reaction.

CPPO

200

This household chemical is the oxidizer that starts the glow-stick reaction 

Hydrogen Peroxide 

300

Used to record changes in chemiluminescence over time, this sensor converts emitted photons into measurable data.
