Chemistry Kinetics: Find the Ea from the difference of temperature

Newcastle Fans

如果而家有哂兩個rate constant (k), 同埋兩個temp, 要搵Ea, 條式應該係點?

ln ( k2 / k1 ) = ( Ea / R ) [ ( 1 / T1 ) - ( 1 / T2 ) ]
ln ( k1 / k2 ) = ( Ea / R ) [ ( 1 / T1 ) - ( 1 / T2 ) ]

邊條先岩? 我同隔離班兩條式唔同

or

ln ( k1 / k2 ) = -[/COLOR]( Ea / R ) [ ( 1 / T1 ) - ( 1 / T2 ) ]
