Acetylsalicylic acid (hc9h7o4) is a weak acid that dissociates in water in the following manner. hc9h7o4(aq) + h2o(l) equilibrium reaction arrow c9h7o4−(aq) + h3o+(aq) at a temperature of 298.15 k, the acid-dissociation constant (ka) for acetylsalicylic acid is 3.3 ✕ 10−4. (a) calculate the change in standard free energy (δg°) for this equilibrium reaction. kj/mol (b) what is the value of δg at equilibrium? δg > 0 δg = 0 δg < 0 (c) if the reaction were spontaneous in the forward direction, what type of value would you expect for δg?
