Pdil 2018 b) T/F Consider the reaction N2+3H2 2NHa. A mixture of 1 mol each of nitrogen and hydrogen gases under the same conditions in a container fitted with a piston. The ratio of volumes of the container (Vfina./Viniris) is ภ331 c) T/FA 4.01 g of sample of a certain diatomic gas occupies a volume of 3.73-L at 1.00 atm and a temperature of 45°C. The gas may be N2 d) T/F state properties. Among pressure, temperature internal energy, enthalpy, work and, heat, 4 of them are e) T/F For the following process which is done constant P and T (P - 1 atm and T 370 K) H20(g) >H2O(U) heat and work are both negative. T/F (1) When solid KBr is dissolved in water, the solution gets colder (2) When concentrated f) Two of the following processes are exothermic: H-S0A is added to water. the solution gets verv high. (3) Water is boiling in a tea kettle T/FIn a process in which one mole of a gas is expanded from state A to state B, the final volum of the gas will not depend on the path taken g) h) T/F The change in enthalpy can always be thought of as equal to energy flow as heat. i) T/F A gamma ray of wavelength 1.00 x 10 cm has enough energy to remove an electron fre a hydrogen atom.
