What will occur when the following chemical reaction reaches dynamic equilibrium? 3H2 + N2 3 2NH3 O A. No further chemical reactions will occur in either direction. B. The concentrations of all reactants and products will be the same C. The product will form at the same rate at which it decomposes. D. The concentrations will continue to change gradually over time.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
