Yes it is possible because, olymorphismis when two or more crystal structures are possible for a material of given composition. Isomerismis when two or more polymer molecules or repeat units have the same composition, but different atomic arrangements.
Answer:
Gamma Rays
Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Explanation:
Given -
T = 450K
∆H = 3000J
∆S = 4J/K
Using formula
∆G = ∆H - T∆S
∆G = 3000- 4*450
∆G = 1200 Joule
∆G is positive so the reaction is non spontaneous!
