The US emerged as a world power in world war 1 first when its economy outgrew that of the other nations due to peace within its borders before entering the war. It happened again when its entry into the war caused a speedy conclusion and victory for the Allies.
It delayed the US entry into the War and gave the Axis powers a chance to mobilize on Great Britain and the US Pacific. A legacy of WWI survivors figured we'd done our share in Europe in 1914-1917 All forms of isolationism dissappeared in the US after Pearl Harbour showed War in Europe could not be ignored.
Most of us may familiar with hotter the better but it is not necessary that catalyst prefer hot temperature. Catalyst do provide alternative path with lower activation energy, and it is not necessary like heat if the trend of overall reaction is exothermic. Many catalyst work best on limited range of temperature not too high and not too low.
The chemical equation is:CH3COOH + C2H5OH ↔ CH3COOCH2CH3 + H2OConcentrated sulfuric acid act as a catalyst.
That's just the way it is you chince deal with it in 1838 was too busy to finish a reaction and because he was in a hurry he chinced the reaction and randomly added Pt. that's how he discovered that Pt was a catalyst through chincing yes, yes I still remember that fine evening on September 30th 1838. we were busy chincing notes in a local geography class when a fellow greaser figured out that Pt was used as a catalyst. This phenomenon left us feeling great and ready to release some loads. kid all u gotta know is some greasers heated out and instead of using the normal catalyst copper they chinced some pt and substituted it.

Because the unexplained explosion was used as a catalyst to precipitate the US and Spain into a war.
Because this was the main reason for the US entry in WW2, and the American entry in the war was significant for the course and outcome, it affected the entire world.
The Franco-Prussian War was not directly related to the entry of the US into World War I.
There are many minor motives for the US entry at the WWII, but the Japanese attack in Pearl Harbor is always refereed as the main one.

do you mean what caused us entry into world war one? if so then the sinking of the USS Lusitania by German u-boats was what caused American entry into the war
sinking lusitania
The Japanese sneak attack on Pearl Harbor propelled the US into the war.
