The rate of disappearance of hbr in the gas phase reaction 2hbr(g) → h2 (g) i2 (g) is 0.190 m s-1 at 150°c. the rate of appearance of h2 is m s-1. group of answer choices

The rate of appearance of hydrogen gas is 0.095 M/s.

Explanation:

Rate of the reaction is the change in concentration of of any one of the reactants or products per unit time.

Given:

The rate of disappearance of HBr =

Rate of the reaction is given by:

Rate of appearance of the hydrogen gas:

The rate of appearance of hydrogen gas is 0.095 M/s.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
