From the reaction P(White) `rarr` P(Red) `Delta H =-18.4KJ`, it follows that :-

From the thermochemical reactions, C(graphite) +1//2O_(2)rarr CO , Delta H = -110.5 KJ CO+1//2O_(2)rarr CO_(2),Delta H=-283.2 KJ the heat of reaction of C(graphite) +O_(2)rarr CO_(2) is :

For the reaction at 298 k,2A +B rarr C, Delta H= 400 KJ mol^(-1) and Delta S=0.2 KJ k^(-1) mol^(-1). At what temperature will the reaction become spontaneous ?

For the reaction x+y rarr p+q the value of Delta H is +a K cal what is the value of Delta H for the reaction p+qradar x+y ?

From the thermochemical reactions, C(grap hite)+1//2O_(2)rarr CO , Delta H =-110.5 KJ CO+1//2O_(2)rarr CO_(2),Delta H=-283.2 KJ The heat of reaction of C(graph ite) +O_(2)rarr CO_(2) is :

for a reversible reaction K_(c )gtK_(p) at 298 K and Delta H = + 200 KJ the forward reaction is not favoured by :

for a reversible reaction K_(c )gtK_(p) at 298 K and Delta H = + 200 KJ the forward reaction is not favoured by :

The chemical reaction : A rarr P, Delta H^(@) = 2.8 kJ is spontaneous only above 400 K. Therefore Delta S of reaction must be at leat (JK^(-1)) .
