Which of the following will favor a spontaneous change? 1.+δh. 2.−δh. 3.+δs. 4.−δs.

will favor a spontaneous change

Explanation:

For a spontaneous reaction, (Change in gibbs free enegy) should be negative.

We know,

where is change in enthalpy for reaction, T is temperature in kelvin scale and is change in entropy for reaction.

T is always positive. Therefore , to make negative, should be negative and/or should be positive

Hence will favor a spontaneous change.

its first and third is your answer i did the qustion the fourth isnt right
