When a reaction is at equilibrium,

the forward and reverse reactions occur at the same rate

all reaction stops

no more reactants are converted to products

the reaction is no longer reversible

the forward and reverse reactions occur at the same rate

Explanation:

A reaction is in chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction.

In equilibrium reaction the concentration of the reactants and products is constant. A reaction is in chemical equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. The chemical equation will be shown as,

α A + β B ⇌ σ S + τ T

2b2t

explanation:

2b2t

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
