Q. The reaction $: A_{(g)} + 2 B_{(g)} \to C_{(g)} + D_{(g)}$ is an elementary process. In an experiment, the initial partial pressure of $A$ and $B$ are $P_{A} = 0.60 a t m$ and $P_{B} = 0.80 a t m .$ When $P_{C} = 0.20$ atm, the rate of reaction relative to the initial rate is:

$\frac{1}{16}$

$\frac{1}{24}$

$\frac{1}{6}$

$\frac{1}{48}$

Since it is an elementary reaction

Rate of reaction $= K (A) (B)^{2}$

Rate of reaction (initial) $= K [0.60] [0.80]^{2} ... (1)$

Rate of reaction (final) $= K [0.40] [0.40]^{2} ... (2)$

$\frac{Rate _{final}}{Rate _{initial}} = \frac{( 0.40 ) ( 0.40 ) ^{2}}{( 0.6 ) ( 0.8 ) ^{2}}$

$= \frac{1}{6}$

Q. The reaction :A(g)​+2B(g)​→C(g)​+D(g)​ is an elementary process. In an experiment, the initial partial pressure of A and B are PA​=0.60atm and PB​=0.80atm. When PC​=0.20 atm, the rate of reaction relative to the initial rate is:

241​

61​

481​

Since it is an elementary reaction Rate of reaction =K(A)(B)2 Rate of reaction (initial) =K[0.60][0.80]2...(1) Rate of reaction (final) =K[0.40][0.40]2...(2) Rate initial ​ Rate final ​​=(0.6)(0.8)2(0.40)(0.40)2​ =61​
