Chemical Engineering Thermodynamics

Q1:

The unity of Planck's constant 'h' in the equation, E = hv is

A J/s

B J.S

C J/kmol

D kmol/J

ANS:B - J.S

The unity of Planck's constant 'h' in the equation 𝐸=ℎ𝜈E=hν (where 𝜈ν represents frequency and 𝐸E represents energy) is J·s (joule-seconds). Planck's constant is a fundamental physical constant that relates the energy of a photon to its frequency. It has units of energy multiplied by time, or joule-seconds. So, the unit of Planck's constant is typically expressed as J·s.
