1.When H2\mathrm{H_2}H2 (gas) gets adsorbed on transition metals, metal hydride formation takes place. Which of the options will not be correct on the basis of the above observation?a.Greater the surface area of transition metals, greater will be the extent of adsorption.b.The enthalpy change involved will be in the range of 202020–40 kJ/mol40\,\text{kJ/mol}40kJ/mol.c.The extent of adsorption first increases with increase in temperature and then decreases.d.The adsorption will be irreversible in nature.Login to continueOnly logged in users canattempt or see the solution.
