Question

energy+socl2(g)=so2(g)=cl2(g),what will happen to the temp?

Answer 1

socl2, cl2 and so2 don't mean a thing to me AND you must have meant for the second = sign to be a + sign. Finally, writing with capitalizing the first letter of the sentence doesn't help me interpret what you want; however, the comma and question mark helped. If you meant

Energy + SOCl2 ==> SO2 + Cl2, it should b obvious that energy is being used by the equation which means there will be less energy around AFTER the reaction and that means a lower temperature.
