reacts slower than hydrogen
Which one of the following statements is incorrect ?
At \( 298.2 \, \text{K} \) the relationship between enthalpy of bond dissociation (in \( \text{kJ mol}^{-1} \)) for hydrogen \(( E_{\mathrm{H}} )\) and its isotope, deuterium, \(( E_{\mathrm{D}} )\), is best described by:
The product obtained from the electrolytic oxidation of acidified sulphate solutions, is:
The single largest industrial application of dihydrogen is:
Given below are two statements:Statement I: The process of producing syn-gas is called gasification of coal.Statement II: The composition of syn-gas is \( \mathrm{CO} + \mathrm{CO_2} + \mathrm{H_2} \) \( (1:1:1) \).In the light of the above statements, choose the most appropriate answer from the options given below:

The INCORRECT statement(s) about heavy water is (are)(A) used as a moderator in nuclear reactor(B) obtained as a by-product in fertilizer industry(C) used for the study of reaction mechanism(D) has higher dielectric constant than waterChoose the correct answer from the options given below:
Isotope(s) of hydrogen which emits low energy \( \beta^{-0} \) particles \( t_{1/2} \) value \( > 12 \) years is/are:
Given below are two statements: One is labeled as Assertion A and the other is labelled as Reason R.Assertion A: The dihedral angles in \( \mathrm{H_2O_2} \) in gaseous phase is \( 90.2^\circ \) and in solid phase is \( 111.5^\circ \).Reason R: The change in dihedral angle in solid and gaseous phase is due to the difference in the intermolecular forces.Choose the most appropriate answer from the options given below for A and R.
