Solution: For the reaction:X → Y Identify what the graphs of [X] versus time and [Y] versus time would look like for various orders.A) Zero-order [X] vs. tB) Zero-order [Y] vs. tC) First or Second-order [X] vs. tD) First or Second-order [Y] vs. t

Problem

For the reaction:

X → Y 

Identify what the graphs of [X] versus time and [Y] versus time would look like for various orders.

A) Zero-order [X] vs. t

B) Zero-order [Y] vs. t

C) First or Second-order [X] vs. t

D) First or Second-order [Y] vs. t

Solution

X → Y  

• concentration of reactant [X] decreases with time (t) - X is consumed to produce product Y
• concentration of reactant [Y] increases with time (t)
• rate law - involves only the reactants
