Chemical Engineering Thermodynamics (MCQs)

An irreversible process

  • A. Is the analog of linear frictionless motion in machines
  • B. Is an idealised visualisation of behaviour of a system
  • C. Yields the maximum amount of work
  • D. Yields an amount of work less than that of a reversible process
Answer: Option D.
Explanation: 
Since always losses are inherint with irreversible process. eg :some of the work done will be lost as either friction loss or intermolecular energy etc. whereas an reversible process takes place in infinitesimal steps so we can neglect losses or consider as no losses so work obtained will be high.
