Acetic acid and ethanol react to form ethyl acetate and water, like this: (aq)(aq)(aq)(l) Imagine of are removed from a flask containing a mixture of , , and at equilibrium, and then answer the following questions. What is the rate of the reverse reaction before any C2H5CO2CH3 has been removed from the flask

Greater than zero, and equal to the rate of the reverse reaction

Explanation:

this is an incomplete question in the first place, i saw the complete format online hence the answer am giving here.

Before any C2H5CO2CH3 is or was removed, the system is said to be in equilibrium.

This means that the rate of consumption of reactants and rate of generation of products are greater than zero and are equal, that means that both the forward and backward reactions are occurs at these rate.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
