Question 1

equilibrium constant (K)

Answer 1

K is a number equal to a particular ratio of equilibrium concentrations of product(s) and reactant(s) at a particular temperature: K = [P_1][…] / [R_1][…] at equilibrium.

Question 2

Haber process

Answer 2

A mechanism to industrially synthesize massive amounts of ammonia which makes use of Le Chatelier’s principle.

Question 3

law of chemical equilibrium (law of mass action)

Answer 3

This says that at a given temperature, a chemical system reaches a state in which a particular ratio of reactant and product concentrations has a constant value: at equilibrium, Q = K

Question 4

Le Chatelier’s principle

Answer 4

When a chemical system at equilibrium is disturbed (meaning that some event causes Q ≠ K), it returns to equilibrium by undergoing a net reaction that reduces the effect of the disturbance ([ ] or pressures change as to reduce the effect of the change in conditions).

Question 5

metabolic pathway

Answer 5

Reaction sequences that categorize the metabolism of a cell: they are processes by which a cell achieves energy flow, breakdown, and synthesis.

Question 6

reaction quotient (Q)

Answer 6

Also known as the mass-action expression, Q is the ratio of the products of product concentrations to the products of reactant concentrations. Q = [P_1][…] / [R_1][…].
