The half-life of a first-order reaction is given by the expression t1/2 = 0.693/k, where k is the rate constant.

The half-life of a first-order reaction is independent of the initial concentration.

The half-life of a first-order reaction is independent of the initial concentration.

The heat capacity at constant volume (Cv) is directly related to the change in internal energy of the system.

The heat capacity at constant volume (Cv) is defined as the amount of heat required to raise the temperature of a substance by 1°C at constant volume.

The heat capacity of a substance is defined as the amount of heat required to raise the temperature of one mole of the substance by one degree Celsius.

The general form of the rate equation is Rate = k[A]^n, where n is the order of the reaction.

If the rate is proportional to the concentration of one reactant raised to the power of 2, the reaction is second order.

This statement defines the rate law of a reaction.

This statement defines the rate law of a chemical reaction.

The overall order of the reaction is 2 (from [A]^2) + 1 (from [B]) = 3.

Adsorption is the process where molecules accumulate on the surface of a solid or liquid.

The uncertainty principle is a fundamental concept in quantum mechanics formulated by Werner Heisenberg.

The diamond structure can be described as a face-centered cubic (FCC) lattice with a basis of two carbon atoms.

Enthalpy (H) represents the total heat content of a system at constant pressure and is defined as internal energy plus pressure-volume work.

Increasing temperature generally increases the rate of a chemical reaction due to higher kinetic energy.

When a balanced equation is multiplied by a factor, the equilibrium constant is raised to the power of that factor.

A catalyst speeds up both the forward and reverse reactions equally, thus it does not change the position of equilibrium or the value of Kc.

The balanced equation in acidic medium is Cr2O7^2- + 6Fe^2+ → 2Cr^3+ + 3Fe^3+.

Fatty acids are the basic structural units of lipids.
