For an exothermic reaction, `DeltaH` is positive.

For an edothemic reaction, DeltaH is positive.

Assertion : DeltaH for an exothermic reaction is negative nad for an endothermic reaction is positive. Reason : Enthalpy is an extensive property.

For a chemical reaction, DeltaH is negative and DeltaS is negative and DeltaS is negative . This reaction is

For an exothermic reaction, what happens to the equilibrium constant if temperature is increased?

For an exothermic reaction to be spontaneous ( Delta S = negative)

Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason). Examine the statements carefully and mark the correct answer according to the instruction given below: STATEMENT-1: The equilibrium constant of the exothermic reaction at high temperature decreases. STATEMENT-2: Since In (K_(2))/(K_(1))=(DeltaH^(@))/(R)[(1)/(T_(1))-(1)/(T_(2))] and for exothermic reaction , DeltaH^(@)= -ve and thereby, (K_(2))/(K_(1))lt1

For an exothermic reaction , temperature increase by 10^@C , the equilibrium constant will

Why is respiration considered an exothermic reaction? Explain.

A : For exothermic reaction, DeltaH=E_a (forward) -E_a (backward) R : The value of activation energy for forward direction is less than activation energy for backward reaction.

Which of the following is true during adsorption? a. DeltaG , DeltaH , and DeltaS all are negative. b. DeltaG is negative, but DeltaH and DeltaS is positive. c. DeltaG and DeltaH are negative, but DeltaS is positive. d. DeltaG and DeltaS are negative, but DeltaH is positive.
