Gen Chem II - Exam 2

Chapters 13.2-14.2

When the original reaction is reversed

K is to the power of negative 1

When the original reaction is added to another reaction

The Ks of both reactions are multiplied

When the original reaction is multiplied by a number

K is to the power of that number
