For a chemical reaction A + B → Product, the order is 1 with respect to A and B . Rate mol L - 1 S - 1 [A] mol L - 1 [B] mol L - 1 0 . 10 20 0 . 5 0 . 40 x 0 . 5 0 . 80 40 y What is the value of x and y ?
Options
- A160 and 4
- B80 and 4
- C80 and 2
- D40 and 4
Correct answer
C. 80 and 2
Step-by-step solution
To determine the values of x and y, we can use the information provided and the rate expression for the given reaction, which is first order with respect to both A and B: Rate r   =   K [ A ] 1   [ B ] 1 0 . 1   =   K ( 20 ) 1   ( 0 . 5 ) 1   … ( i )   0 . 40   =   K ( x ) 1   ( 0 . 5 ) 1   … ( ii )     0 . 80   =   K ( 40 ) 1   ( y ) 1   … ( iii ) From (i) and (ii) x   =   80 From (i) and (iii) y &
