For the reaction 2A+B`rarr`C at 298 K, `DeltaH=400kJ mol^-1` and `DeltaS=0.2 kJk^-1mol^_1`. At what temperature will be reaction become spontaneous considering `DeltaH` and `DeltaS` to be constant over the temperature range.

For the reaction, 2Cl(g) rarr Cl_2(g) what are the signs of DeltaH and DeltaS ?

For the reaction: 2AZ_(g) + B_(g) rarr 2D_(g) DeltaU^@ = -10.5 kJ//mol DeltaS^@ = -44.1 kJ//mol at 298 K. Calculate DeltaG^@ for the reaction.

For the reaction Ag_2O -> 2Ag+ frac{1}{2} O_2 (g) DeltaS and Delta H are 6.66J K^-1mol^-1 and 30.56 kJ mol^-1 respectively. The reaction will not be spontaneous at what temperature

A reaction has value of Delta H = -40 kcal mol^(-1) at 400 K. Below 400 K the reaction is spontaneous and above 400 K it is not. The value of DeltaG and Delta S at 400 K are respectively

For the reaction 2A(g)+B(g) rarr2D(g), DeltaU^theta =-10.5 kJ and DeltaS^theta=-44.1Jk^-1 Calculate DeltaG^theta for the reaction and predict whether the reaction may occur spontaneously.

Delta H and DeltaS for the reaction Ag_2O (s) iff 2Ag(s)+ 1/2O_2(g) are 30.56 kJ mol^-1 and 66.0 JK^-1 respectively. Calculate the temperature at which the reaction would be at equilibrium. Also predict the direction of the reaction above this temperature.
