Accepted Answer
The order of a reaction describes how the rate of a reaction changes with the concentration of the reactants. It is determined experimentally and can be zero, first, second, or even fractional order.
Molarity (M) is a unit of concentration that represents the number of moles of solute per liter of solution. For example, a 1 M solution of sodium chloride (NaCl) contains 1 mole of NaCl dissolved in 1 liter of water.
To calculate the volume of oxygen, you can use the ideal gas law: PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is temperature in Kelvin. First, convert the mass of oxygen (25.0 g) to moles using its molar mass (32.00 g/mol). Then, convert the temperature from Celsius to Kelvin (20°C + 273.15 = 293.15 K). Finally, plug the values into the ideal gas law equation and solve for V.
