(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. The rate of a reaction is independent of temperature. Fast reactions can be slowed down by lowering the temperature. Reaction rates increase as reactant concentrations decrease. Reaction rate constants are independent of temperature. Reaction rates always increase as masses of solid reactants increase. Reaction rates are determined by reactant (oncentrations, temperatures, and reactant stabilities. flask is charged with 0.120mol of A and allowed to react to form B according to the following hypothetical gas-phase reaction. A(g)B(g) The following data are collected. (a) Calculate the number of moles of B at each time in the table. os mol 40= mol 805 mol 1205 mol 1605 mol (b) Calculate the average rate of disappearance of A for each 405 interval, in units of mol/s
