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

A Glass pipet
Explanation:
The best laboratory equipment to measure out exactly 4.0mL of a liquid is a pipet.
The pipet is a glass tube with a suction as tthe top.
- It is designed for measuring small units of volume accurately.
- Once dipped into the fluid, the suction is pressed and the liquid gushes in.
- When released, the liquid fills the tube.
- The suction can be pressed at regular intervals to release the liquid till the desired volume is attained.
