Thermodynamically it is favourable for diamond to turn into graphite, but it do not normally happen because there is high energy of activation for the process. So, option b is correct.

Answer:
Statement-1: Diamonds are forever is generally quoted for diamond as the rate of conversion of diamond to graphite at room conditions is nearly zero.
Statement-2: At room conditions, the conversion of diamond into graphite is spontaneous.
Explanation:
Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
To understand the correctness of the given options, let's analyze each statement individually.
Statement-1: Diamonds are forever is generally quoted for diamond as the rate of conversion of diamond to graphite at room conditions is nearly zero.
Diamonds are considered to be one of the hardest substances known to man. They are formed from carbon atoms arranged in a crystal lattice structure. This unique structure gives diamonds their exceptional hardness and durability. The conversion of diamond to graphite involves a rearrangement of carbon atoms from a tightly packed lattice structure to a loosely packed layered structure.
Under normal conditions, the rate of conversion of diamond to graphite is extremely slow. This is due to the high activation energy required for the conversion process to occur. Activation energy is the energy required to initiate a chemical reaction. In the case of diamond to graphite conversion, the activation energy is so high that the rate of conversion is negligible at room conditions. Therefore, diamonds are considered to be "forever" as they are extremely stable and resistant to degradation.
Statement-2: At room conditions, the conversion of diamond into graphite is spontaneous.
The statement that the conversion of diamond into graphite is spontaneous at room conditions is incorrect. Spontaneous processes are those that occur without the need for external intervention or the input of energy. In the case of diamond to graphite conversion, the process is not spontaneous at room conditions. It requires a significant input of energy to overcome the activation energy barrier.
The correct explanation for the stability of diamonds lies in the unique arrangement of carbon atoms in the diamond lattice. The strong covalent bonds between carbon atoms in the lattice make it difficult for the atoms to rearrange and convert into graphite. This is why diamonds are highly resistant to degradation and have a negligible rate of conversion to graphite at room conditions.
Therefore, the correct answer is option 'B' - Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.
Statement-1: Diamonds are forever is generally quoted for diamond as the rate of conversion of diamond to graphite at room conditions is nearly zero.
Statement-2: At room conditions, the conversion of diamond into graphite is spontaneous.
Explanation:
Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
