Which of the following is true for the equilibrium constant of a reaction? its value remains constant at different temperatures. it is a ratio of coefficients of reactants to products. it is represented by the symbol k. its value is always less than 1.

It is represented by the symbol K.

Explanation:

1. Its value remains constant at different temperatures:

It is wrong because it depends on the T and varies by varying the T.

2. It is a ratio of coefficients of reactants to products:

It is wrong because It is a ratio of coefficients of products to reactants.

3. It is represented by the symbol K:

It is right, since it is represented by the symbol K.

4. Its value is always less than 1:

It is wrong, because it may be equal, less or more than 1 depends on the reaction components.

it is represented by the symbol k

Explanation:

Just took the test

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
