Consider the following brønsted acid-base reaction at 25°c: hf(aq) + cl−(aq) ⇆ hcl(aq) + f−(aq) (a) predict whether k will be greater or smaller than 1. it will be greater than 1. it will be smaller than 1. (b) does δs o or δh o make a greater contribution to δg o ? δs o makes a greater contribution. δh o makes a greater contribution. they both contribute equally. (c) is δh o likely to be positive or negative? it is likely to be positive. it is likely to be negative. it is not possible to know.
