Question

For the reaction A + 2B 3C, if the rate of disappearance of B at time is 0.8 wto molts* then the rate
of appearance of C at time t is
(1) 0.4 x 10-mol L-s1
(2) 0.8 x 104 mol L-4 st
(3) 1.2 x 10-mol L-15-1
(4) 1.6 * 104 mol L-​

Answer 1

Answer:

ANSWER

A+2B⇌2C

2 3 1 (t=0)

2−x 3−2x x+2 (t=t)

Now [C]=1.0 mole/L=x+2

⇒x=1−2=−1

⇒[A]=2−x=2−(−1)=3

[B]=3−2x=3−2(−1)=5

& [C]=x+2=−1+2=1

K=

[A][B]

=

(3/2)(5/2)

=

3/2×25/4

1/4

=

75

(Dividing moles by volume)

⇒K=0.0267
