Answer to Question #299886 in General Chemistry for Victoria

Question

( which answer is correct )

An example of a system at dynamic equilibrium is:

A) the steady colour of the hottest Bunsen-burner flame

B) the steady temperature of water boiling in an open beaker

C) a piece of magnesium metal in a beaker of hydrochloric acid

D) a glass of water with a lid on it

Answer 1

Dynamic equilibrium is a situation where a reaction reaches a state in which the rate of reaction going one way is exactly the reaction going in the reverse.

An example is a glass of water with a lid on it.

At a particular temperature, the rate of evaporation of water is equal to the rate of condensation
