Question 1

What is a homogeneous reaction

Answer 1

a reaction in which all of the reactant and products are in the same phase

Question 2

what is the equilibrium constant

Answer 2

a number that expresses the relationship between the number of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature

Question 3

subscript “eq” indicates

Answer 3

concentration at equilbruim

Question 4

what is the only factor that affects equilibrium constant

Answer 4

temperature

Question 4

what are two ways you can calculate equilibrium constant

Answer 4

1. experimentally
2. calculations using thermodynamics

Question 5

for wA + xB ⇌ yC + zD what is the equation for the Equilibrium constant

Answer 5

[D]^z[C]^y/[A]^w[b]^x

Question 6

what is a heterogeneous reaction

Answer 6

a reaction where at least one of the products/reactants is in a different phase than others

Question 7

the concentration of a solid is determined by

Answer 7

its density

Question 8

why is the density of a solid result in its exclusion in the Kc formula

Answer 8

the denisty of a solid is constant and it determines its concentration so the concentration of a solid is constant making it be excluded
