Answer 1

products Rate Constant = 0.0380 Mstat 300°c Zero-ooder Reaction : [A] + = [A]o - kt) where - [A] = Concentration of A at "t's TA] = 'Concentration of Aat" to k=rate Constanta Griven: - k = 0.0380M51 [A]o = 0.870M [A] = 0.280 M 0.280 M = 0.870M -0.0380 xt 0°0380 t 0.0380 t = 0.870 - 0.280 = 0.590 - t = 15°53 s l = 15.538 would it take for the Concentration of a todecrease 10-870M to 0. 280 M.
