Question 4.31

Postby Sean Ezenwugo 3J » Sun Feb 28, 2016 9:06 pm

In part of the answer explanation, it's stated that Ea1 > Ea2 and therefore k1 < k2 .
How does one come to that conclusion? Why isn't k1 greater than k2 ?

Using the Arhenius Equation k=A*e^-E/(RT) we can determine that E is inversely proportional to k. In other words if E increases k will decrease and if E decreases k will increase. Thus we can conclude that if the activation energy of reaction 1 is larger than the activation energy of reaction two, then the k constant of reaction 1 is smaller than the k constant of reaction 2.
