Consider the reaction below. h2(g) + co2(g) mc013-1.jpg h2o(g) + co(g) at equilibrium at 600 k, the following are true. [co2] = 9.5 x 10-4 m [h2] = 4.5 x 10-2 m [h2o] = 4.6 x 10-3 m [co] = 4.6 x 10-3 m what is the value of the equilibrium constant for this reaction in correct scientific notation? 4.9 x 10-3 4.9 x 10-2 4.9 x 10-1 4.9 x 103

Ans: c) 4.9 *10-1

Given:

Concentrations of the reactants and products-

[CO2] = 9.5 x 10-4 M

[H2] = 4.5 x 10-2 M

[H2O] = 4.6 x 10-3 M

[CO] = 4.6 x 10-3 M

To determine:

The equilibrium constant K

Explanation:

The given reaction is:

H2(g) + CO2(g) ↔ H2O(g) + CO(g)

The equilibrium constant is given as:

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
