The instruction booklet for your pressure cooker indicates that its highest setting is 12.8 psi . You know that standard atmosph

Answer:At $237.57^oC$ food will cook in the pressure cooker set on high.

Explanation:

Standard atmospheric pressure $P_1$ = 14.7 Psi = 1.0001 atm (1 Psi=0.06804 atm)

Standard temperature $T_1$ = 273.15 K

Highest pressure offered by pressure cooker: 12.8 Psi = 0.8709 atm

Pressure ( $P_2$ ) inside the pressure cooker on the highest setting at temperature $T_2$ :

$P_2$ = 1.0001 atm + 0.8709 atm = 1.8710 atm

According to Gay lussac law :

$(pressure)\propto (temperature)$ (at constant Volume)

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

$T_2=\frac{P_2\times T_1}{P_1}=\frac{1.8710 atm\times 273.15 K}{1.0001 atm}=510.73 K= 237.57^oC (T(^oC)=T-273.15 K)$

At $237.57^oC$ food will cook in the pressure cooker set on high.

The rate of disappearance of HBr in the gas phase reaction 2 HBr(g) → H2(g) + Br2(g) is 0.140 M s-1 at 150°C. The rate of appear

djverab [1.8K]

Answer: The rate of appearance of $Br_2$ is $0.0700Ms^{-1}$

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

$2HBr(g)\rightarrow H_2(g)+Br(g)$

The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.

Rate in terms of disappearance of HBr = $-\frac{1d[HBr]}{2dt}Rate in terms of appearance of [tex]H_2$ = $\frac{1d[H_2]}{dt}$
