### Help on HW 4.30 and the Arrhenius Equation

Posted:

**Sun Mar 05, 2017 10:09 pm**The question asks: "The activation energy in organic reaction is known to be 125 kJ/mol. Will this reaction occur at room temperature?"

How do I calculate this? I assumed we would use the Arrhenius equation and solve for k, and if k is less than 1, then the reaction wouldn't occur under room temperature. However, A isn't given. (Another question, is A always supposed to be given, or is there an equation to solve for A other than the Arrhenius equation?)
