`G_(1) to S` transition is regulated by

Given (at 25^(@)C and 1 atm pressure): C(s, diamond) +O_(2)(g)toCO_(2)(g),DeltaH^(0)=-393.5kJ*mol^(-1) C(s, graphite) +O_(2)(g)toCO_(2)(g),DeltaH^(0)=-391.6kJ*mol^(-1) Find the standard heat of transition from graphite to diamond.

The enthalpy of transition of crustalline boron to amorphous boron at 1500^(@)C is 0.4 kcal "mole"^(-1) . Assuming at.wt of boron 10, the change in enthaplpy of transition 50 g boron from crystalline to amorphous form is

Find the value of "a" if the phase transition temperature in Kelvin for the conversion of grey tin to white tin is found to be "100 a ". Delta H_("transition")=21kJmol^(-1) Delta S_("transition")=70Jmol^(-1)K^(-1)

Let R and S be two relations on a set A. If (iii). R and S are both transitive on A prove that R cap S is transitive but R cup S is not necessarily transitive on A.

A relation R_(1) is defined on RxxR rarr RxxR by (a, b)R_(1)(c, d) implies a+b+c+d is positive. How many statements S_(1), S_(2), S_(3), S_(4) are CORRECT ? S_(1) : Relation is Reflexive but not Symmetric S_(2) :, Relation is Symmetric but not Transitive S_(3) : Relation is Transitive but not Symmetric S_(4) : Relation is Equivalence (A) 0 (B) 1 (C) 2 (D) 4

A relation R_(1) is defined on RxxR rarr RxxR by (a, b)R_(1)(c, d) implies a+b+c+d is positive. How many statements S_(1), S_(2), S_(3), S_(4) are CORRECT ? S_(1) : Relation is Reflexive but not Symmetric S_(2) :, Relation is Symmetric but not Transitive S_(3) : Relation is Transitive but not Symmetric S_(4) : Relation is Equivalence

For an isothermal reversible phase transition process , Delta S is

The correct statement(s) about transition element is/are.

If R and S are transitive relations on a set A , then prove that RuuS may not be a transitive relation on A .
