All three phases can exist in an equilibrium with one another at the __ of a substance
1 answer:
Answer:
Triple point
Explanation:
Yes, all three phases can exist in an equilibrium with one another at the triple point of a substance.
In thermodynamics, the triple point of a substance is defined as the point at which all three phases of substance co-exist together at a particular pressure and temperature.
for example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.
And for water it is 0.01 °C and 611.73 pascals.
you will get some clear idea after seeing the graph.
And critical point as you see in the graph is end point of phase equilibrium curve, mainly liquid-vapor equilibrium

The time required to reduce the concentration from 0.00757 M to 0.00180 M is equal to 1.52 × 10⁻⁴ s. The half-life period of the reaction is 9.98× 10⁻⁵s.
<h3>What is the rate of reaction?</h3>The rate of reaction is described as the speed at which reactants are converted into products. A catalyst increases the rate of the reaction without going under any change in the chemical reaction.
Given the initial concentration of the reactant, C₀= 0.00757 M
The concentration of reactant after time t is C₁= 0.00180 M
The rate constant of the reaction, k = 37.9 M⁻¹s⁻¹
For the first-order reaction:
0.00180 = 0.00757 - (37.9) t
t = 1.52 × 10⁻⁴ s
The half-life period of the reaction:
Half-life of the reaction = 9.98 × 10⁻⁵s
