A chemical reaction is conducted at 2 different temperatures. When the reaction is conducted at 400 K, the reaction constant was measured as 2.50*10^-6 M^-1s^-1. If the activation energy of the reaction is 2.35*10⁵ J/mol, what would the reaction constant of the reaction be if it was conducted at 500 K? (Please provide your answer to 3 significant figures.)
