Temperature coefficient refers to the ratio of rate constant of a chemical reaction, affected by 10 degree rise in temperature. It is represented as Kt 10degree/Kt. Therefore, option 'B'is the correct answer.

Kt 10/Kt is known as

The correct answer is B) temperature coefficient.

Explanation:

Kt is the thermodynamic equilibrium constant of a reaction. It is defined as the ratio of the product of the concentrations of the products raised to their stoichiometric coefficients to the product of the concentrations of the reactants raised to their stoichiometric coefficients.

Kt 10/Kt is a dimensionless quantity that is used to describe the effect of temperature on the equilibrium constant of a reaction. It is called the temperature coefficient (Q10) and is defined as the ratio of the equilibrium constant at a certain temperature to the equilibrium constant at a temperature 10 degrees Celsius lower.

The temperature coefficient is used to estimate the effect of a change in temperature on the equilibrium constant of a reaction. A positive temperature coefficient indicates that the equilibrium constant increases with increasing temperature, while a negative temperature coefficient indicates that the equilibrium constant decreases with increasing temperature.

In summary, Kt 10/Kt is known as the temperature coefficient and is used to describe the effect of temperature on the equilibrium constant of a reaction.
