Question

A process is in equilibrium state when
A) ∆G >0
B) ∆G=0
C) ∆G=1
D) ∆G=2

Answer 1

B is the correct answer.

Answer 2

A process is in equilibrium state when ∆G= 0 ( Option B is the correct answer)

• Chemical equilibrium is the condition of a system where the concentrations of the reactants and products remain constant across time and where the characteristics of the system remain unchanged.
• There are both forward and backward reactions. Such processes maintain consistent reactant and product concentrations when the forward and reverse reaction speeds are comparable.
• This stage of the reaction is known as chemical equilibrium. As opposed to previous equilibriums, this one is regarded to be dynamic.
• This is as a result of the fact that it includes both a forward reaction in which the reactants react to make products as well as a reverse reaction in which the products may react to produce the original reactants.
• When temperature and pressure are both constant, a system is in equilibrium when G=0.

ΔG=ΔG° +RTlnK

When, ΔG=0,

ΔG° =−RTlnK

Hence, a process is in equilibrium state when ∆G= 0
