At 450°C ,the Kp for the reaction N2(g)+ 3 H2(g) 2NH3(g) is 4.5 x 10-5 . For each mixture listed,indicate whether the mixture is at equilibrium at 450°C. If it is not at equilibrium,indicate the direction (toward product or toward reactants) in which the mixture must shift to achieve equilibrium.
Write a program in C++ to find the largest and smallest of N numbers of any data type (use function overloading). The value of N is available only at the time of execution
A 300. mg sample of caffeine was dissolved in 10.0 g of camphor (Kf = 39.7 °C/m), decreasing the freezing point of camphor by 3.07 °C. What is the molar mass of caffeine?
