For cases where [A] exactly doubles: • if the rate does not change, the order for A is 0. • if the rate doubles, then the order for A is 1. •if the rate quadruples, the order for A is 2. For more complex cases, use the general equation: order [reactant], = (- ` [reactant], ratej rate2 What is the reaction order with respect to A?

Write the following number using decimal notation: seven and forty-three thousand fifty-two millionths. Converting Decimals to Fractions Note that each of the decimals you have encountered thus far in this activity end after a few digits. Decimals such as these are referred to as terminating decimals. When a terminating decimal is written as a fraction or mixed number, the denominator corresponds to the place value of the rightmost digit in the decimal. This leads to the…
