When a mixture of potassium chlorate and an appropriate catalyst is heated in an open test tube, potassium chloride and oxygen gas are produced. This reaction is not reversible because a the reaction does not go to completion b the system reaches equilibrium c the system is closed d the oxygen escapes

d the oxygen escapes.

Explanation:

Hello there!

In this case, according to the given information, it turns out firstly convenient for us to write out the chemical reaction taking place:

Thus, since both potassium chlorate and chloride are solid whereas oxygen is gaseous, it tends to scape as we are working in an open test tube and that is why the products side do not have the reactants, KCl and O2, to return the reactants side, KClO3 in agreement to the concept of equilibrium reaction. This situation can be solved by working in a closed container.

Therefore the answer is d the oxygen escapes.

Regards!

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
