just wanted to clarify a few things before the exam..hope someone can help
okay so,
1) the rate constant is only affected by temperature right?
2) when the temp increases and the Kc value decreases = exothermic (forward reaction)
when the temp increases and the Kc value increases = endothermic (forward reaction)
(Kc only affected by temp)
3)Could anybody explain the actual role of the salt in buffer reactions, i know it dissociates to produce the conj. base but is that it?
(im just going through the spec, so il write some more if theres anything else that slightly bothers me)
good luck everyone!
