Re: k and Ea
you can think about it this way... the equilibrium constant k is basically products/reactants. If the activation energy is super high, then it's harder to form products since we have to first overcome this barrier. So when the numerator is smaller, k is smaller.

Re: k and Ea
The larger the value of k is, the faster the rate. If Ea is large, more energy is required for the reaction to occur, which means the rate will be slower. If the rate is slower, k will be smaller.

Re: k and Ea
k is small because if the activation energy is high, it will be harder for the reaction to produce products

Re: k and Ea
You can see the relationship by looking at the equation: k=Ae^(-Ea/RT); an e to a small number will give you a small k, whereas an e to a big number will give you a large k. In other words, the bigger Ea is, the smaller the value of k will be and vice versa.
