Thus, sound will travel at a slower rate in the denser object. If sound waves of the same energy were passed through a block of wood and a block of steel, which is more dense than the wood, the molecules of the steel would vibrate at a slower rate. Thus, sound passes more quickly through the wood, which is less dense.

bromine gas and nitric oxide can combine to form nitrosyl bromide, nobr. br2 (g) 2 no (g) ⇌ 2 nobr (g) if the reaction has reach
Vadim26 [7]

The reaction would shift to the right (forward).

Balanced chemical reaction: Br2(g) + 2NO(g) ⇌ 2NOBr(g)

According to the Principle the position of equilibrium moves to counteract the change.

The equilibrium shift to the right, so more product (nitrosyl bromide) will be produced. If the product is removed, the reactants will react to produce that product and set equilibrium.

Concentration of the reactants (bromine gas and nitric oxide) is reducing, while concentration of product is increasing.

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.

Speed of direct and irreversible chemical reaction are equal
