Why wiens law is called wiens displacement law?

Wiens Law is known as Wiens Displacement Law because it describes the relationship between the temperature of a blackbody radiator and the peak wavelength of the radiation it emits. It shows how the peak wavelength shifts to shorter values at higher temperatures and vice versa, hence the term "displacement."

Pressure and volume changes at a constant temperature can be calculated using?

Boyle's Law, which states that pressure and volume are inversely proportional at a constant temperature, expressed as PV = constant. Mathematically, this can be written as P1V1 = P2V2, where P represents pressure and V represents volume at different points in the process.

How do you calculate the restoring force according to Hookes law?

To calculate the restoring force according to Hooke's Law, you can use the formula F = -kx, where F is the restoring force, k is the spring constant, and x is the displacement from the equilibrium position. By multiplying the spring constant with the displacement, you can determine the magnitude and direction of the restoring force acting on the object.


What must be known for the rate constant to be calculated from the rate law?

The reaction rate at known reactant concentrations.


What gas law is used to calculate the pressure of gas at various volume assuming temperature stays constant?

The ideal gas law, also known as the combined gas law, is used to calculate the pressure of a gas at various volumes assuming constant temperature. This law states that the pressure of a gas is inversely proportional to its volume when temperature is constant. Mathematically, it is represented as PV = constant.


Calculate the initial rate for the formation of rm C at 25 rm circ C if rm A0.50 M and rm B0.075 M?

To calculate the initial rate, you need to know the rate law for the reaction. From there, you can plug in the initial concentrations of A and B to determine the rate constant. Without the rate law, it's not possible to calculate the initial rate.
