Chapter 1 - Foundations Flashcards
What is 2 mol in avagadro’s number?
1.2 * 10^24
When does a reaction reach equilibrium?
When the forward and reverse rates of a reaction are equal
What is the formula of a high energy molecule that carries electrons and can be used to generate ATP
NADH
When a steady state is reached, all intermediate concentrations have to be equal (T/F)
T
When a steady state is reached, do the concentrations of the substrate and product have to be equal?
NO
Name 3 components of the cell theory
- All living organisms are made of cells
- A cell is the smallest unit of life
- All cells arise from other cells
Which 2 types of cells do NOT contain DNA
Red blood cells, platelets
What is the theory of spontaneous generation and who proved it wrong? What theory did this discovery lead to?
theory: living organisms arise from nothingness.
Louis pasteur proved that bacteria exists in air. This led to the cell theory
What is the theory of vitalism and is it correct?
Living systems do not obey the same chemical principles as inert materials
What is the meaning of avagadro’s number??
Number of molecules or atoms in 1 mole of a substance
What is the collision theory?
The rate of a reaction is proportional to the number of collisions
What is kf?
the rate constant
The rate constant is independent of changes in _______ but is affected by _____ and ______
independent of changes in concentration, but is affected by temperature or ionic strength
What is the classical approach of thermodynamics?
uses a few postulates and definitions but makes no assumptions about the exact nature of the systems. Even the existence of molecules is unnecessary
What is the statistical approach of thermodynamics?
considers the behavior of large collections of molecules. More narrowly applicable than the classical approach
