Benzene be B

Toluene be T

We have made then one lettered to make things easier

  • \sf P^0_B=95.1mmHg,P^0_T=28.4mmHg
  • \sf x_B=x_T=0.5

\\ \rm\Rrightarrow \dfrac{P^0_B-P_B}{P^0_B}=x_B

\\ \rm\Rrightarrow 95.1-P_B=95.(0.5)

\\ \rm\Rrightarrow 95.1-P_B=47.55

\\ \rm\Rrightarrow P_B=47.55mmHg

And

\\ \rm\Rrightarrow \dfrac{P^0_T-P_T}{P^0_T}=x_T

\\ \rm\Rrightarrow 28.4-P_T=28.4(0.5)

\\ \rm\Rrightarrow P_T=14.2mmHg

Total vapour pressure

  • 28.4+95.1
  • 123.6mmHg

The decomposition of hydrogen peroxide (H2O2(aq)) is proposed to follow a reaction mechanism of: Step 1: H2O2(aq) + Br–(aq)→H2O(
lys-0071 [83]

Answer:

Option (1) Br– is the catalyst, and the reaction follows a faster pathway with Br– than without

Explanation:

Let us consider the equation below:

Step 1:

H2O2(aq) + Br–(aq) → H2O(l) + BrO–(aq)

Step 2:

BrO–(aq) + H2O2(aq) → H2O(l) + O2(g) + Br–(aq)

From the above equation, we can see that Br– is unchanged.

This implies that Br– is the catalyst as catalyst does not take part in a chemical reaction but they create an alternate pathway to lower the activation energy in order for the reaction to proceed at a much faster rate to arrive at the products.

8. Thermal Energy is?
Burka [1]

Thermal energy is the sum of the kinetic and potential energy of all the particles in an object. The figure shows that if either potential or kinetic energy increases, thermal energy increases.
