Which of the following processes occurs in the reaction given below C _ (graphite) C _ ( g ) ?

Options

  1. AVaporisation
  2. BFusion
  3. CSublimation
  4. DIonisation

Correct answer

A. Vaporisation

Step-by-step solution

The reaction C _ (graphite) C _ ( g ) represents the direct transformation of solid carbon into gaseous carbon. Vaporization and fusion describe liquid-gas and solid-liquid phase transitions respectively, while ionization involves electron transfer. Sublimation specifically denotes the direct solid-to-gas transformation without an intermediate liquid phase. This corresponds precisely to option C.
