For the reaction R to P, a graph of [R] against time is found to be a straight line with negative slope. What is the order of reaction ?

Answer»

SECOND ORDER
Third order
First order
ZERO order

Solution :(d) : For zero order reaction, `k=(1)/(t)[[A]_(0)-[A]]" or "[A]=[A]_(0)-kt`
Thus, plot of [A] vs t is straight line with NEGATIVE slope.
