A sample of nitrogen gas at 298 K and 0.980 atm has a volume of 37.42 L. What volume will it occupy if the pressure is increased to 1.176 atm at constant temperature?
Acetaldehyde decomposes at 750 K: CH3CHO â†' CO + CH4. The reaction is first order in acetaldehyde and the half-life of the reaction is found to be 530 seconds. What is the rate constant for the reaction at this temperature?
A sucrose (table sugar, molar mass 342 g/mol) solution was made by dissolving 68.2g of sucrose in 800 g of water. What is the freezing point of this solution if Kf of water is 1.86 degrees C/Molal?
