<em>Determine if the following statements are true or false. </em>
<em>The rate law for an overall reaction can be written using the coefficients from the overall reaction.</em> FALSE. The rate law includes the reaction orders, which have to be determined experimentally and may or may not be equal to the coefficients of the overall reaction.
<em>The rate-determining step of the reaction is always the first step of the reaction.</em> FALSE. The rate-determining step is always the slowest step.
<em>A catalyst is a species that is added to the reaction, lowers the activation energy of a reaction, shows up in the rate law (most of the time), and will be in the overall balanced equation.</em> FALSE. A catalyst does lower the activation energy of the reaction, but it doesn't show up in the rate law nor the overall balanced equation.
Yuri Oganessian has already discovered the next noble gas at atomic weight 118, (which is 86 plus 32). The next most likely, if ever encountered, should be 150 (which is 118 plus 32) or at 168 (which is 118 plus 32 plus 16).
