Acertain process has δh° > 0, δs° < 0, and δg° > 0. the values of δh° and δs° do not depend on the temperature. which of the following is a correct conclusion about this process? none of the above conclusions is correct. it is non-spontaneous at all t. it is spontaneous at low t. it is spontaneous at all t. it is spontaneous at high t

It is non-spontaneous at all T.

Explanation:

According to Gibb's equation:

= Gibbs free energy = +ve

= enthalpy change  = +ve

= entropy change  = -ve

T = temperature in Kelvin

= +ve, reaction is non spontaneous

= -ve, reaction is spontaneous

= 0, reaction is in equilibrium

Putting in the values:

Reaction is non spontaneous at all temperatures.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
