This reaction is zero order with respect to A because the concentration of A doesn't affect the rate of the reaction. The order with respect to B is 2 - it's a second order reaction with respect to B. The reaction is also second order overall (because 0 + 2 = 2).Example 3: This reaction is first order with respect to A and zero order with respect to B, because the concentration of B doesn't affect the rate of the reaction.The reaction is first order overall (because 1 + 0 = 1).his rate will decrease during the reaction as A gets used up. Summary For the purposes of rate equations and orders of reaction, the rate of a reaction is measured in terms of how fast the concentration of one of the reactants is falling. Its units are mol dm-3 s-1.
Notes: The rates above are for regular corporate taxes based on income (including those called franchise taxes) and exclude the effect of alternative taxes and minimum taxes. Most states have a minimum income or franchise tax.
Average tax rates measure tax burden, while marginal tax rates measure the impact of taxes on incentives to earn, save, invest, or spend. The average tax rate is the total amount of tax divided by total income. For example, if a household has a total income of $100,000 and pays taxes of $15,000, the householdâs average tax rate is 15 percent. The marginal tax rate is the incremental tax paid on incremental income.
