The equilibrium-constant expression depends on the of the reaction. (a) stoichiometry (b) mechanism (c) stoichiometry and mechanism (d) the quantities of reactions and products initially present (e) temperature

(A) stoichiometry

Explanation:

For example, Consider the reaction of the type ,

aA + bB> cC +dD

where b, a, d, and c are the stoichiometric coefficients for the balanced equation .

The equilibrium constant expression is denoted by K ,

equilibrium constant is the product's concentration each raised to the power of its corresponding stoichiometries , divided by reactant's concentration each raised to the power of its corresponding stoichiometries .

e

explanation:

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
