For the allotropic change represented by...

For the allotropic change represented by the equation C (graphit) `rarr` C (diamond), `Delta H = 1.9 kJ`. If 6g of diamond and 6 g of graphite are separately burnt to yield `CO_(2)`, the enthalpy liberated in first case is

A

less than in the second case by 1.9 kJ

B

more than in the seocnd in first case is

C

more than in the second case by 0.95 kJ

D

less than in the second case by 11.4 kJ

Text Solution

Verified by Experts

The correct Answer is:
C

(More energy released in case of diamond)
Energy released `=1.9/12xx6 =0.95 kJ`

For the change, C_("diamond") rarr C_("graphite"), Delta H = -1.89 kJ , if 6 g of diamond and 6 g of graphite are separately burnt to yield CO_2 the heat liberated in first case is:

For the change C (diamond) rarr C(graphite) , Delta H=-1.89 KJ, if 6 g of diamond and 6g of graphite are seperately burnt to yield CO_(2) the heat liberated in first case is :

For the change, C_("diamond") to C_("graphite"), DeltaH = -1.89 kJ , if 6g of diamond and 6g of graphite are separately burnt to yield CO_2 , the heat liberated in first case is

The enthalpy change for chemical reaction is denoted as DeltaH^(Theta) and DeltaH^(Theta) = H_(P)^(Theta) - H_(R)^(Theta) . The relation between enthalpy and internal enegry is expressed by equation: DeltaH = DeltaU +DeltanRT where DeltaU = change in internal enegry Deltan = change in number of moles, R = gas constant. For the change, C_("diamond") rarr C_("graphite"), DeltaH =- 1.89 kJ , if 6g of diamond and 6g of graphite are seperately burnt to yield CO_(2) the heat liberated in first case is

For the transition C (diamond) rarr C (graphite), Delta H = - 1.5 kJ it follows that

The enthalpy change for the process C("graphite") rarr C(g) is called
