Urea (NH2CONH2) is the end product in protein metabolism inanimals. The decomposition of urea in 0.1 M HCl is first order inurea and first order overall. When [urea] = 0.200 M , the rate at61.0 °C is
8.56 x 10-5 M/s. What is the concentration of urea in this solutionafter 4751 s if the starting concentration is 0.500 M ?

NH2CONH2 + HCl + 2H2O ? 2NH4 Cl + HCO3-
