Question

write the equation for Kc. [C+O=CO2]​

Answer 1

Answer:

Correct option is 4.0

The equilibrium reaction is C(s)+CO 2

(g)⇋2CO(g).

The expression for the equilibrium constant is K p = P CO 2

P CO2

Substitute values in the above expression.

K p = PCO 2

P CO2 =

4.0(4.0) 2=4.0.

Answer 2

Explanation:

Step-by-step explanation:

We have , tanA = 1

= A = 45°

2 sin A cos = 2 sin 45° cos 45°

= 2× 1/√2 × 1/√2 = 2/2 = 1

or

1 - tan ^ 30° / 1 + cot ^ 30 °

= 1 - {1/1/√3 } ^ / 1 + ( √ 3) ^

= 2/3/ 1+3

= 2/12

= 1/6
