For reaction `2Cl_((s)) to Cl_(2(s)),` the signs of `Delta H "and " Delta S` respectively are _______ .

A

`+,-`

B

`-,-`

C

`+,+`

D

`-,+`

Text Solution

Verified by Experts

The correct Answer is:
B
Reaction is spontaneous. `Delta S` must be -ve. `Delta G` must -ve. `Delta G= Delta H- T Delta S`. Hence `Delta H` must be + ve.

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

Consider the reacton C(s) + (1)/(2) O_(2)(g) rarr CO(g) + 200 kJ The signs of Delta S and Delta G respectively are

Delta H and Delta S for the reaction, Ag_(2)O(s)to 2A(s)+(1)/(2)O_(2)(g) , are 30.56 kJ mol^(-1) and 66.0 J mol^(-1) respectively. Calculate the temperature at which this reaction will be at equilibrium. Predict whether the forward reaction will be favoured above or below this temperature.
