0 Entropy is a measure of the (1) acidity of a sample (2) disorder of a system (3) concentration of a solution (4) chemical activity of an element

Calculate ΔG in kJ•mol-1 at 298 K for the following reaction:  2 A(g) + B2(s)  →  2 AB(g)    ΔGo = 49 kJ•mol-1  under the following conditions:   P(A) = 0.446 atm, P(AB) = 0.823 atm     A certain reaction A → B has a rate constant of 4.7 x 10–2 M s-1 at 25°C. An experiment was run at this temperature where the initial concentration of A is 0.342  M. What is the half-life of the reaction in seconds? (the answer should be entered with 3 significant figures; do not enter units; give answer in normal notation--examples include 1.23 and 120. and -123 and 123. and 12.3)
