which one of equations below represents a reaction that is feasible at all temperatures?
a. P(s) -> Q(s) + R(g) endothermic
b. 2L(g) + M(g) -> 2N(g) exothermic
c. S(g) ->2T(g) exothermic
d. A(g) + B(g) -> C(g) endothermic
thanks plz explain

✔ 最佳答案
the following is just my WILD GUESSIt have to be feasible at all temp.So, I considered 0K and a extremely high temp,at 0K, no heat
endothermic rxn. should not be able to carry out.
a and d is eliminated.
exothermic rxn. still ok
left b and cthen consider an exteremely high temp. say 10^100000000000
break bond easy, form bond difficult (absord heat is easy, release heat is difficult)b: break bond and form bond
c: break bond onlySo, I guess it is C.
Tell me if I'm wrong
