Do you expect `triangleS to be +ve, -ve or zero for reaction :
`H_2(g)+I_2(g)⇌2HI(g)`

For the reaction : 2Cl(g)-.Cl_2(g) .

Predict whether /_\S is +ve or -ve for the following reaction. ) 2H_(2(g))+O_(2(g))rarr2H_2O_((g))

Complete the reactions. PH_(3)(g) +O_(2)(g) rarr

triangleH for the reaction, H(g)+H(g)rarrH_2(g) will be,

triangleS for the reaction, MgCO_3(s)rarrMgO(s)+CO_2(g) will be

Give the bond energies of N equiv N, H-H and N-H bonds as 945, 436 and 391 kJ mol^-1 respectively, the enthalpy of the following reaction N 2(g) ​ +3H 2(g) ​ →2NH 3(g) ​ is:

If the enthalpy change for the reaction CH_4(g)+Cl_2(g)rarrCH_3Cl(g)+HCl(g) , triangleH =-25 kcal. Bond energy of C-H is 20kcal/mol greater than the bond energy of C-Cl and bond energies of H-H and H-Cl are same in magnitude, then for the reaction: 1//2H_2(g)+1//2Cl_2(g)rarrHCl(g) triangleH is

trianglen , the change in the number of mole for the reaction, C_12H_22O_11(s)+12O_2(g)rarr12CO_2(g)+11H_2O(l) at 25^@C is
