Nice quiz. I'm a chemical engineer. Two issues. Ethylene or Ethene is the gas that helps in the ripening of fruit. It's a member of the Alkene homologous series. Acetylene or Ethyne is an Alkyne. Very different. Ice cubes melting is both an endothermic and reversable process.
@@rajarajacholan1-ym6mv Ice cubes can melt by increasing heat, or by decreasing the pressure. And they can freeze by decreasing heat or increasing pressure. You can pretty much keep doing this for as long as you want. Which makes it a reversible process

Yes . But are the questions wrong?
It can't be reversible it is not spontaneous
